RuleBase serialization fails with StackOverflowError
----------------------------------------------------
Key: JBRULES-946
URL: http://jira.jboss.com/jira/browse/JBRULES-946
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.0.MR2
Reporter: Alexandre Gattiker
Assigned To: Mark Proctor
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.

Mark Proctor commented on JBRULES-946:
--------------------------------------
Is this easily reproducible? Can I reproduce this with the single rule above, or do I need
920 variations? If the later, then you'll need to provide me with a self contained
project, that I can run to re-produce this.

New subject: [JBoss JIRA] Commented: (JBRULES-946) RuleBase serialization fails with StackOverflowError
[ http://jira.jboss.com/jira/browse/JBRULES-946?page=comments#action_12368177 ]
Alexandre Gattiker commented on JBRULES-946:
--------------------------------------------
I apologize, my report was somewhat lacking. The class below allows to reproduce the bug.
It is easily reproducible, in my project I have a large rulebase and I can reproduce the
bug by serializing even non-overlapping chunks of it.
The example here crashes with 2000 rules (JDK 1.5.0_08 on Linux) and will even crash with
only 1000 rules on JDK 1.6.
Also, if the number of rules is increased to 3000, the serialization crashes with a
single-line error message "java.lang.OutOfMemoryError: Java heap space".
The introduction of JBoss Rules in our project has yielded an amazing speed increase, and
being able to persist our rule base would be the icing on the cake! Thank you very much
for your work.

RuleBase serialization fails with StackOverflowError
----------------------------------------------------
Key: JBRULES-946
URL: http://jira.jboss.com/jira/browse/JBRULES-946
Project: JBoss Rules
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.0.MR2, 4.0.0.MR3
Reporter: Alexandre Gattiker
Assigned To: Mark Proctor
Fix For: 4.0.0.MR4
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.

Michael Neale commented on JBRULES-946:
---------------------------------------
Thanks for the excellent test to reproduce it ! (one nice feature of eclipse - copy all
the source from above into the clipboard, and then past it into an eclipse project and it
will create the right file for you !). So kudos for taking the time to provide a test.
FYI, for me on linux, JVM 1.5 - I don't get the error. But mark does - on his Windows
machine.
So we will find a solution for this.
Some things to try as work arounds are to increase the stack by using -Xss2048k.

RuleBase serialization fails with StackOverflowError
----------------------------------------------------
Key: JBRULES-946
URL: http://jira.jboss.com/jira/browse/JBRULES-946
Project: JBoss Rules
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.0.MR2, 4.0.0.MR3
Reporter: Alexandre Gattiker
Assigned To: Mark Proctor
Fix For: FUTURE
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.

Fix For: 5.3.0.M1
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.

RuleBase serialization fails with StackOverflowError
----------------------------------------------------
Key: JBRULES-946
URL: https://issues.jboss.org/browse/JBRULES-946
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.0.MR2, 4.0.0.MR3
Reporter: Alexandre Gattiker

Fix For: 5.4.0.Beta2
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.

Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.

Fix For: 5.5.0.CR1
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new
InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly
fine and working.
