Hi Alessio.

There is inconsistency in WS .sh/.bat files in jboss-as/bin between Native and CXF stack.

All WS Native .sh files in EAP contain JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true", but WS CXF .sh files not.
All WS Native .bat files in EAP contain set JAVA_OPTS=%JAVA_OPTS% -Djava.net.preferIPv4Stack=true, but WS CXF .bat files not.

Chnages in WS Native .sh/.bat files are done in EAP build process, see [1] and search for IPv4Stack. JBPAPP-2868 is tracking JIRA for this change. Regarding JBPAPP-2868 comments EAP 5.1 does not support IPv6.

CXF zip is not influenced by EAP tag build process, it's just dependency. Changes need to be done in WS CXF EAP branch [3].

I suggest to the the same changes in WS Native EAP branch [2] too and than later remove IPv4 string replace target in build-distr.xml from EAP branch [1] - I can do that.

Alessio, what do you think about it?
