Hmm.
What I've been noticing is that after APT reported a few errors (that
is, if the source code contains errors), it will start to break the
interface contract and return null where it's not supposed to, and it
eventually kills JAXB like this.
But if you haven't seen any error message before this happens, then this
might be another bug.
Is there any chance you can attach a debugger to Ant (you can do that by
doing export ANT_OPTS="-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,address=8000" then run Ant), and
see what is null in APTNavigator.java:391? The JAXB RI distribution
should have all the source bundles you need.
Or if you can send us the test case, that would be great, too.
