Memory leak when deploying to Maven repository?
by Sandjaja, Dominik
Hello everybody,
I use Drools to create rules from an external source and create an artifact from those rule strings, putting it into a local repository.
A minimalistic working example can be found at https://github.com/dadadom/MavenMemoryLeakMinimalExample
The code, taken from that example, is basically like this:
ReleaseId releaseId = new ReleaseIdImpl("some:releaseid:1.0.0-SNAPSHOT");
String rules = "rule \"testrule\ ... ";
KieServices kServices = KieServices.Factory.get();
KieFileSystem kfs = kServices.newKieFileSystem();
kfs.write("src/main/resources/someBase/testrule", rules);
kfs.generateAndWritePomXML(releaseId);
String kmoduleXmlString = "<kmodule ... </kmodule>";
kfs.writeKModuleXML(kmoduleXmlString.getBytes());
KieModule kieModule = kServices.newKieBuilder(kfs).getKieModule();
try {
File pomFile = new File(System.getProperty("java.io.tmpdir"), "pom.xml");
try (FileOutputStream fos = new FileOutputStream(pomFile)) {
fos.write(KieBuilderImpl.generatePomXml(releaseId).getBytes()); fos.flush();
} catch (IOException e) {
e.printStackTrace();
}
final MavenRepository mavenRepository = MavenRepository.getMavenRepository();
mavenRepository.deployArtifact(releaseId, (InternalKieModule) kieModule, pomFile);
When I call this method in a ServletContextListener in a Tomcat Server (version 7 or 8) and undeploy the application afterwards, I get a memory leak.
Tomcat tells me that the application has a memory leak:
The following web applications were stopped (reloaded, undeployed), but their
classes from previous runs are still loaded in memory, thus causing a memory
leak (use a profiler to confirm):
/mvntest
Looking at the memory dump with e.g. JProfiler, I can trace the dangling instances back to an object
static INSTANCE of class org.drools.compiler.kie.builder.impl.KieRepositoryImpl
So it seems like there is something which I am either missing or which is a bug. I cannot find any .close() or .release() method or something alike on any of the involved objects ...
If anyone could give me a hint how to solve this problem, I'd be happy not to litter my memory no more :)
Regards and thanks
Dominik

drools leaving a backgroud thread
by Aliza Itzkowitz (Silver) (aitzkowi)
Hi,
I have a Java servlet running on Tomcat7 which runs multiple drools knowledge bases with a session associated to each one.
I am using drools version 6.1.0.Beta3
When tomcat shuts-down I am seeing this message in the log:
Jun 10, 2014 6:39:36 PM org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
SEVERE: The web application [/MyRulesServlet-1.0-SNAPSHOT] created a ThreadLocal with key of type [org.drools.core.common.UpgradableReentrantReadWriteLock$1] (value [org.drools.core.common.UpgradableReentrantReadWriteLock$1@5c0bf171<mailto:1@5c0bf171>]) and a value of type [org.drools.core.common.UpgradableReentrantReadWriteLock.LockRequestCounter] (value [org.drools.core.common.UpgradableReentrantReadWriteLock$LockRequestCounter@141860ed<mailto:LockRequestCounter@141860ed>]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
It seems I am not performing a proper cleanup of resources on shutdown.
I am calling kSession.dispose() for all the sessions I have, but apparently this is not enough.
What else do I need to do to get rid of this background thread?
Thanks,
Aliza

Hi,
I am deploying Drools Workbench with VFS Clustering in place. I have followed the steps defined in Drools-6 documentation in section "VFS-CLUSTERING", and the following link. But my repositories are not synching
http://mswiderski.blogspot.com.br/2013/06/clustering-in-jbpm-v6.html
but getting following Zookeeper exception.

Problem
BPMN process created in Workbench-A is not getting Synched with Workbench-B. Following are the screen shots for the difference in project assets. Images attached in "ServerAssets.png"

Are there second-rate fact types?
by Wolfgang Laun
Consider:
class Foo { /*...*/ }
rule checkFoo
when
Foo( noSuchField > 0 )
then ... end
DRL compilation reports an error (Error: unable to resolve method ...)
and identifies rule, line and column, which is fine.
Now let's look at:
import java.util.ArrayList;
rule checkArrayList
when
ArrayList( noSuchField > 0 )
then ... end
The same DRL compiler (checked with 5.5.0 and 6.0.0) accepts this, and
there is a nasty exception thrown at runtime. This is inconvenient,
since the exception can be thrown by any code inserting an ArrayList
object, and the faulty rule isn't identified.
Why are certain classes second-rate?

Drools Workbench - Cloning a local Repo Gives “Invalid remote: origin”
by Zahid Ahmed
Hi,
I am trying to clone a repo in Drools WorkBench and getting the following error,
"Can't clone repository. java.lang.RuntimeException:Invalid remote: origin"
The repository which I am cloning, resides in my local machine. D:/Servers/Drools-6-Deployment/repo/repoA.git
Following are the inputs I am providing to WorkBench clone Wizard,
"Repository Name = repoCloned" "Organizational Unit = inTech"
"GIT URL = file:///D:/Servers/Drools-6-Deployment/repo/repoA.git"
"User Name = " (Currently I am giving my github account cred. What to give in user name?)
"Password = " (Currently I am giving my github account cred. What to give as password?)
Question 1
Why am I getting remote origin error when I am cloning from a local GIT repository ?
Question 2
Kindly let me know what to give as User Name and Password when I am cloning from an existing GIT repo in my local filesystem ?
Regards,
Zahid Ahmed

Parallel / Distributed Optaplanner
by jonathan.labin
I know that this topic has come up before. At various times there were
responses indicating that it was being considered at some level within the
project(s).
How has that played out? Was there progress or has the idea been put on the
back-burner? Was something discovered that seems to make the idea not worth
pursuing?
I'm contemplating doing some investigating of my own to attempt to leverage
additional hardware in a distributed way for our application. But I didn't
want to end up re-discovering things or try things that have already proved
to be a dead end by an effort ongoing within the project.
Any insight you could share?

Drools Pluggin Syntax Check
by vdesai
I have installed Drools Pluggin in Eclipse and have installed pluggin -
JBoss Drools Core and related ones.
However, it doesnt complain/error about errors in the typo or bracket issues
for trules. is there anything i am missing or needs to install other
features which will validate Drools files as good as Java Class for syntax.
The Pluggin/Features should validate all brackets, typo erros, reference
java classes and all dependencies.
Appreciate the input.
