[jboss-jira] [JBoss JIRA] (DROOLS-711) Kie Server unable to build KieBase which builds fine with kie-maven-plugin and unit test

[Petr Široký (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13040195#comment-13040195 ] 

Petr Široký commented on DROOLS-711:
------------------------------------

I have been able to reproduce the issue. I am not sure what is the root cause though, will need to look more closely later.

See for example http://stackoverflow.com/questions/27207454/drools-6-1-0-final-cep-example-unable-to-create-field-extractor where similar issue is discussed. What is weird in this case is that the behavior is different for standalone test and kie-server.

>          Issue Type: Bug
>    Affects Versions: 6.2.0.CR4
>         Environment: kie-server on WildFly 8.2.0.Final running with JDK 8
>            Reporter: Matteo Mortari

> I have deployed Kie Server kie-server-distribution-wars-6.2.0.CR4-ee7.war on WildFly 8.2.0.Final.
> I have a simple rule base in the project {{client-test-rules}} as per below, in a kie project structured as kie-drools-archetype, which passes all test and install in m2 repo with {{mvn clean install}}.
> {code:java}
> package com.acme.client_test_rules;
> declare Measurement
>  @role(event)
> end
> rule "keep latest Measurement ID"
> salience 1000
> no-loop
> when
>     $old : Measurement( $id : id )
>     $new : Measurement( id == $id , this after $old  )
> then
>  System.out.println("keep latest old : "+$old+" new (kept): "+$new);
>     retract($old);
> end
> {code}
> Then I issue Kie Server commands, using the client library, using project {{client-test}} to instantiate a container for the same artifact, but in the wildfly logs I get the following error below - which doesn't happen for kie-maven-plugin nor during unit test. Please note I'm assuming user {{kieserver}} with password {{kieserver}} is a valid user for the Kie Server Realm, or configure wildfly or the code in the project {{client-test}} accordingly to your environment =).
