Summary: CCE on redeployment of ear with sar/ejb
Initial Comment:
The perf-service.ear in the current main testsuite is
not usable across redeployments. Steps to reproduce:
1. Deploy the perf-service.ear and then execute the
jboss.test:service=PerfTest runTests(100) operation.
Ignore the NPE shown under testTimings.
2. Simply touch the perf-service.ear and then execute
the runTests(100) operation again on the
jboss.test:service=PerfTest mbean, you will see:

The most recent PerfTest mbean output shows clearly what
the problem is. On the initial deployment and execution of
the runTests operation, both the ProbeHome interface as
seen by the proxy bound in JNDI and the class reference in
the PerfTest service mbean are seen to be loaded from the
same perf.jar location:
ProbeHome Interfaces:
++interface org.jboss.test.perf.interfaces.ProbeHome
++++CodeSource: (file:/D:/usr/local/src/cvsroot/Main/jboss-
all/build/output/jboss-3.0.0DR2/tmp/deploy/62.60.perf.jar )
++interface javax.ejb.Handle
++++CodeSource: (file:/D:/usr/local/src/cvsroot/Main/jboss-
all/build/output/jboss-3.0.0DR2/tmp/deploy/6.jboss-
j2ee.jar )
PerfTest ProbHome CodeSource:
(file:/D:/usr/local/src/cvsroot/Main/jboss-
all/build/output/jboss-3.0.0DR2/tmp/deploy/62.60.perf.jar )
After a new deployment of the perf-service.ear, the proxy
bound in JNDI continues to reference the ProxyHome class
loaded from the original perf.jar, while the PerfTest
service mbean ProbeHome now refers to the new perf.jar
deployment:
ProbeHome Interfaces:
++interface org.jboss.test.perf.interfaces.ProbeHome
++++CodeSource: (file:/D:/usr/local/src/cvsroot/Main/jboss-
all/build/output/jboss-3.0.0DR2/tmp/deploy/62.60.perf.jar )
++interface javax.ejb.Handle
++++CodeSource: (file:/D:/usr/local/src/cvsroot/Main/jboss-
all/build/output/jboss-3.0.0DR2/tmp/deploy/6.jboss-
j2ee.jar )
PerfTest ProbHome CodeSource:
(file:/D:/usr/local/src/cvsroot/Main/jboss-
all/build/output/jboss-3.0.0DR2/tmp/deploy/68.66.perf.jar )
The JNDI bindings of the proxies are not being updated
correctly on redeployment.

I notice that you can redeploy many times successfully as
long as you don't run the test. Once you have run the test,
after redeploying, the test fails.
deploy
redeploy
redeploy
run test (succeeds)
redeploy
run test (fails)
