I'm seeing the following log statement if i turn the loglevel to debug:

This happens because of the WSS4J library. I am wondering if i need to take any action. If i understand it correctly 2 providers have been added but adding the bouncycastle fails. I know that i could add the bc libs to jboss or jre but is this really necessary? The fact that it is "only" a debug statement makes me also wonder if it is necessary. Maybe somebody knows what this actually means and can help me.
WSS4J attempts to install the BouncyCastle provider if it is available, and logs that DEBUG level error if it is not (this behaviour will change in the next major release). There is nothing to worry about if you don't require BouncyCastle to be installed.

I spent a whole bunch of time today working out a problem that occurred on migrating from Optaplanner 7.48 to Optaplanner 8.3.0 The problem seems to me to be actually in the 7.50 version of Drools that Optaplanner 8.3 depends on.
rule "applyHomeTeamConstraints"
enabled true
when $f1: ProblemFixture(slot != null, $ht: homeTeam)
$tu: ProblemSoftConstraint(this memberOf $ht.constraints,
matches($f1.slot.dateTime) )
then
scoreHolder.penalize(kcontext, -$tu.getWeight());
end
The rule worked perfectly happily in Optaplanner 7.48/Drools 7.48.
When I use this rule in my Optaplanner 8.3.0/Drools 7.50 project, I get an exceptionally unhelpful message...
java.lang.IllegalStateException: There is an error in a scoreDrl or scoreDrlFile.
at uk.me.selwyn_family.league.scheduler.solver.SolverTest.testBuildSeasonSolver(SolverTest.java:47)
Caused by: java.lang.UnsupportedOperationException
at uk.me.selwyn_family.league.scheduler.solver.SolverTest.testBuildSeasonSolver(SolverTest.java:47)
After many hours of tracing I found that the exception was actually thrown at line 243 in org.drools.modelcompiler.builder.generator.expressiontyper.ExpressionTyper
Expression parentLeft = findLeftLeafOfNameExpr(halfPointFreeExpr.getParentNode().orElseThrow(UnsupportedOperationException::new));
and occurs because the parentNode is null.
I can solve the problem by simply add this. in front of the matches() as follows...
rule "applyHomeTeamConstraints"
enabled true
when $f1: ProblemFixture(slot != null, $ht: homeTeam)
$tu: ProblemSoftConstraint(this memberOf $ht.constraints,
this.matches($f1.slot.dateTime) )
then
scoreHolder.penalize(kcontext, -$tu.getWeight());
end
I am trying to work out whether it was only working by accident in the 7.48 version and actually should never have worked or whether a bug has crept into the Drools 7.50 that should be reported.
Either way a more helpful error message would be good!
Any suggestions gratefully received.
Update: Now I have told Surefire not to trimStackTrace here is the full trace...

(No wonder it took me a long time to trace!!!)
This sounds like a regression in Drools. Yes, that error message isn't helpful - that too is an issue (note that Drools has improved a lot to get better error messages and the new way to write constraints (ConstraintStreams) has far more useful stacktraces).
One thing that doesn't make sense to me is your stacktrace:
java.lang.IllegalStateException: There is an error in a scoreDrl or scoreDrlFile.
at uk.me.selwyn_family.league.scheduler.solver.SolverTest.testBuildSeasonSolver(SolverTest.java:47)
Caused by: java.lang.UnsupportedOperationException
at uk.me.selwyn_family.league.scheduler.solver.SolverTest.testBuildSeasonSolver(SolverTest.java:47)
This stacktrace doesn't mention lines of org.optaplanner or org.drools. Can you please share the code of SolverTest.java:47 too so we can verify it doesn't covert/eat the exception? The message does seem to come from OptaPlanner, but a true OptaPlanner exception would have a chained (= caused by) exception coming from a line in org.drools with hopefully more information for us to diagnose why it doesn't give a proper error message.
I am trying to use the Business-Central/Workbench module. Followed the instructions as provided in the [Getting Started][1] of jBPM. I tried with all the pre-defined logins. Nothing works.
It throws
I also tried to look into the application-roles.properties and application-users.properties files. Both seems to be empty (only comments).
The error is something like:

Finally figured out the issue. It is:

This pointed to an incompatible JDK. I downgraded from JDK14 to JDK11.
I've installed WSO2 Integration Studio version 6.5.0 in my Windows workstation and created a project using the Kafka Consumer and Producer built-in template.
Then I configured the project with my own Kafka server settings (topic name "myTopic").
I then right-clicked the composite application and chose Export Project Artifacts and Run.
The Console window displayed at the very top the following messages:

I've tried uninstalling Integrator Studio and running it with elevated right to no avail.
I expected the project to be deployed normally.

Have you copied the required jars from kafka_home/libs folder to EI_home/lib, if yes then share your code to get the issue detail
According to this documentation https://docs.wso2.com/display/EI650/Kafka+Inbound+Protocol, the recommended versions for Kafka is kafka_2.9.2-0.8.1.1. You can download it in the below link. http://kafka.apache.org/downloads.html. Please use those jars and copy them to the EI_HOME/lib. There is an github issue for this as well. https://github.com/wso2/product-ei/issues/2239
I may be a bit too late but we have been using Custom inbound endpoint for Kafka. We also faced exactly same issue and that was the only way to fix it.
You could use https://github.com/wso2-extensions/esb-inbound-kafka/blob/master/docs/config.md to configure it.
I'm using Jboss EAP 7.1 and when i try to dumpAllModuleInformation from ServiceModuleLoader, i'm getting null pointer exception, however i could see results for LocalModuleLoader. Attaching the Stack Trace below.
Basically i'm trying to see all loaded resources for my war file. I'm really not sure what's the reason for null pointer exception. All other operations like dumpModuleInformation, getDependencies, getModuleDescription, getModulesPathInfo, refreshResourceLoaders, relink and unLoadModule throwing IllegalArguementException: Module specification is null. Only queryLoadedModuleNames is returning my war filenames. Application is running fine without any issues. Jconsole is also throwing the same exception. I need to find a way to see all loaded jars for my war file. Standalone server is hosted with multiple war files, so planning to write a JMX program to get loaded dependencies for all of my wars/ears. Can you guys help me on this

I am trying to deploy my gwt app to tomcat6 under ubuntu 9.10 and get
the (i suppose known to many of you)
"java.security.AccessControlException: access denied" error (Full
exception can be found at the end). I have searched the net in general and found that the Java default security
permissions are preventing the serializer from accessing my classes
private members (they do have getters and setters) and that i should
add to tomcat policy with a file at /etc/tomcat6/policy.d/60gwt.policy
the following:
grant codeBase "file:/var/lib/tomcat6/webapps/-" {
permission java.security.AllPermission;
}
Although i have done that (and i understand the implications) i still
get the same error, no matter how many times i restart the server. The
next step would problably be to disable tomcats security manager
completely but this app will eventually go into production and i d
like to know what's going on here. Also, i'd rather not make any
member variables public...
Any ideas?
cheers
