The one thing I see is that maven spaws a javadoc process and waits
for it to finish. It probably doesn't set a timeout. If this process
blocks for some reason, your build will block.

You appear to be on Unix, do you have a hang javadoc process
somewhere? If so, kill it and see if your build process goes on
(obviously with a failed build).

If that works, consider adding a timeout option to your

   at org.apache.commons.jelly.tags.ant.AntTag.doTag(AntTag.java:195)

for that kill operation to be performed automatically).

Not yet.  I a couple of months I can.

BTW, a later hang up was in a jUnit test (at least a jUnit test error was
reported when I killed the java process).

I tried to get a thread dump from that process, but I can't find it.  Where
does standard out go when running jUnit tests (in another jvm)?
