Ant build script

Description of problem:

Running the JAXB xjc task in ant appears to make ant fail at a later stage with
classpath problems. The xjc task itself seems to finish correctly.

The background to this is trying to build Netbeans on Fedora 27 fails and I
have done some work to narrow down Netbeans build script (which is very
large/complicated) to this aspect.
See https://issues.apache.org/jira/browse/NETBEANS-239 and
http://mail-archives.apache.org/mod_mbox/incubator-netbeans-dev/201801.mbox/...

However setting the ANT_HOME explicitly makes this bug disappear.

I believe I have set up the xjc task correctly to run with Fedora's
glassfish-jaxb packages.
