I just recreated this locally on master when trying to fix a changeset issue.

Here's the issue:
  https://issues.jboss.org/browse/JBRULES-3457

Did you build the binary package in Guvnor?

There was a big change to the serialization of packages in Drools Expert.

Hi I tried deploying guvnor 5.4 CR1 on jboss 7.1.1 final. I downloaded the package and tried running the program using it. I'm getting the following exception:

I doubted if my code was causing the issue, so I took a fresh guvnor 5.4 CR1 and installed the sample repository (mortgages) and tried to run sample code to check. I'm getting the same issue

code I used to get the knowledgebase

 KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
        kbuilder.add( ResourceFactory.newUrlResource("http://127.0.0.1:8380/drools-guvnor/mortgages.pkg"), ResourceType.PKG );
        KnowledgeBuilderErrors errors = kbuilder.getErrors();
        if (errors.size() > 0) {
            for (KnowledgeBuilderError error: errors) {
                System.err.println(error);
            }
            throw new IllegalArgumentException("Could not parse knowledge.");
        }


Can someone guide me through this.

Yeah I can download the package... I'll try by using the pkg file... Thanks for the help :)

About the connection error. I can't find a way to reproduce it. I'll keep trying and let you know if I find something.

Can you download the package directly from Guvnor? You could test the jitting error with that.

Thanks Toni..... Eagerly awaiting for your response :)

I'll check if there is a bug in Guvnor. It could cause the SocketException.

Can you let me know if I missed anything while migrating to CR1?? Thanks in advance.

Hi Mario...
            This exactly, seems to be the problem..... I'm getting the exception exactly at 21st record. I'll try it on CR1 in a while.

In the 5.4 we decided to do the (biggest part of) constraints evaluation with
MVEL. Then, for performance reason, after a constraint has been evaluated a
given amount of times (20 at the moment), we JIT the constraint transforming
it in a proper Java class via ASM. You got an exception during this last
JITting process. Sorry if I cannot be more precise, but I'd need to
reproduce your problem to exactly figure out what was wrong.

Anyway, give it a try with the CR1 and if the problem persists please let me
know, possibly also sending at least the rule containing the constraint that
generated the problem (metricclass == "PROCESSOR" in your case), and the
Java bean or declared type related to the constraint itself.
