Your setup looks good, perhaps changing the configure script to run ant
with -debug would help?

Configuring with --with-java does nothing other than build the JDBC
driver. There used to be some additional java tools, but these were
removed before the 7.4 release. The provided jar files are no different
than what you would build yourself so it's fine to use them.
