Description Ivo Bek 2014-02-28 09:51:01 UTC 
Description of problem:

When I redeploy Business Central, I will get the following exception:

IllegalStateException: There's already another KieContainer created from a different ClassLoader
	at org.drools.compiler.kie.builder.impl.KieServicesImpl.getKieClasspathContainer(KieServicesImpl.java:82)
	at org.drools.compiler.kie.builder.impl.KieServicesImpl.getKieClasspathContainer(KieServicesImpl.java:67)
	at org.drools.compiler.cdi.KieCDIExtension.init(KieCDIExtension.java:74)
	at org.drools.compiler.cdi.KieCDIExtension.processInjectionTarget(KieCDIExtension.java:81)

I get this exception also when I want to deploy my own application which uses a kie container, so it is not possible to use both at the same time.

I suggest to look at the modules which have changed a lot.

Version-Release number of selected component (if applicable):

1. Have a clear installation of BPMS 6.0.1.ER1

Alexandre already fixed a duplicate of this issue. Reassigning to him to double check that is the same thing and eventually close.

Verified in BPMS 6.0.1.ER2

It is possible to redeploy Business central and also have an own kie application together with Business central.
Comment 6 Ivo Bek 2014-03-11 08:55:04 UTC 
I have to reopen this issue because the problem is still there. Yes, it is possible to redeploy Business central. Also it is possible to have own kie application together with Business central.

The problem is that it is not possible to redeploy own kie spring application. I get:

Caused by: java.lang.IllegalStateException: There's already another KieContainer created from a different ClassLoader
	at org.drools.compiler.kie.builder.impl.KieServicesImpl.getKieClasspathContainer(KieServicesImpl.java:83) [drools-compiler-6.0.2-redhat-4.jar:6.0.2-redhat-4]

I will attach the spring application. To reproduce the issue, all you need to do is:

1) create spring module - just extract springframework.zip into modules/system/layers/base/org
2) start BPMS 6.0.1.ER2
3) deploy springapp.war
4) undeploy springapp.war
5) deploy springapp.war once again
6) see the exception above

btw: you'll have to update springapp.war with most recent spring integration in order be able to test it.
