Mark, Turns out it is a JDK bug.
http://www-01.ibm.com/support/docview.wss?uid=swg1IV99686 https://bugs.openjdk.java.net/browse/JDK-8177809 While it has been fixed, we currently are required to support AIX 6.1, which doesn't have an updated JDK because IBM no longer supports that version of AIX.

If so, I'd recreate this while running Tomcat with a remote debugger and put a break point in org.apache.catalina.startup.ExpandWar.expand(Host,URL,String) to see exactly what is going on. Unfortunately, there isn't any additional logging available.
