Thomas, this test case has been there since JBoss 4.0. It is run under the JACC configuration. Currently there are issues when the JBoss instance is bound to an IP address. I am wondering if you can take a look at the deployment descriptors for this test case in AS5 test suite to see if it is tied to localhost.....
The way to start the jacc target is summarized in the first post of the following thread.
Your test is the last in the list. The entire suite of tests take around 8-10m.
I think there are two tests failing in this JBWS309 test wherein remoting fails to make connection.
After the first run of the target, your JACC server config is created, so you can follow the regular procedure, if you wish from the second time onwards:
./run.sh -b your_ip_address -c jacc
ant -Dtest=org.jboss.test.webservice.jbws309.JBWS309TestCase one-test
