JBossWS - Incorrect undeployment of WAR (with jbossWS) directory

When I deploy a WAR directory (by copying it into server's deploy dir) which contains jboss web service and then delete it (undeploy), I get an exception, same as deploy/undeploy with JBDS. EAP then gets into inconsistent state - (<server>jbossws/services shows registered endpoint, but the WSDL is not reachable)
This applies only to directory WAR, tried on WAR archive with same content and everyting OK.
I'll attach server log.
What I did (check log):
1. Start default configuration
2. copied sample.war into deploy dir
3. deleted sample.war form deployDir
4. unzipped sample.war into SampleWS.war dir
5. copied SampleWS.war dir into deploy dir
6. deleted SampleWS.war dir
7. terminated server
Reproducible : Always
