Issue with ServletClientBusTestCase - testSingleDeploy (CXF testsuite)

I noticed issues with ServletClientBusTestCase - testSingleDeploy on IBM jdk. I was able to simulate it locally on IBM and Sun JDK. The issue occurs only when the AS has fresh start and no other test was executed. I start AS and run ServletClientBusTestCase for the fist time - it fails. But when I executed test for the second/third/fourth time it passes. Something must be internally initialized within the first run and so the next runs passes.

My steps to reproduce:

• start EAP 5.1.2.ER1
• run mvn -e -Djboss510.home=/home/rsvoboda/TESTING/jboss-eap-5.1-CXF/jboss-as -Pjboss510,hudson,testsuite test -Dtest=org.jboss.test.ws.jaxws.cxf.bus.ServletClientBusTestCase — test fails
• run the test again and it passes
