[jboss-jira] [JBoss JIRA] (JBRULES-946) RuleBase serialization fails with StackOverflowError

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 Assignee: Mark Proctor Fix For: 5.5.0.Beta1 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. java.lang.StackOverflowError at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java(Compiled Code)) at
