Description Aleksandar Kostadinov 2011-04-06 13:59:24 UTC 
project_key: SOA

I see [SerialVersionUIDUnitTestCase|https://hudson.qa.jboss.com/hudson/view/SOA-Release/job/soa-eap/95/testReport/org.jboss.test.compatibility.test/SerialVersionUIDUnitTestCase%28tests-compatibility%29/test404Compatibility/] JBoss AS test case fail.

Actually the following three classes have a different serial version UUID from what JBoss AS 4.0 has.
edu.emory.mathcs.backport.java.util.Collections$AsLifoQueue
edu.emory.mathcs.backport.java.util.Collections$ReverseComparator
edu.emory.mathcs.backport.java.util.concurrent.TimeUnit

These classes were in jboss-backport-concurrent.jar in JBoss AS 4. These classes are NOT present in JBoss EAP 4.3 CP09. These classes are present in SOA-P in backport-util-concurrent.jar

So since these classes seem not needed with java 5+ can we remove backport-util-concurrent.jar from SOA-P?

Comment 2 Len DiMaggio 2011-04-08 14:51:37 UTC 
Before we move with this JIRA - question - where did the file come from? And do we know why/how it was added in CP05?

Comment 3 Julian Coleman 2011-04-12 15:04:47 UTC 
Need to investigate if jBPM will compile/run with the .../jboss-as/client/concurrent.jar from EAP.
Comment 4 (please assign to mrietvel@redhat.com) 2011-09-01 11:38:36 UTC 
jBPM 3 is java 4 compliant -- which is why backport-util-concurrent is used and not newer java 5+ implementations of the same classes. 

Aleksandar's comment above is spot on: backport-util-concurrent was added because of fixes to the JobExecutor implementation. 

Because of this, I don't think it's possible to remove backport-util-concurrent from SOA-P.
