Ah... right. It's not a problem that 1.5 is being used to compile it.
The build.xml files get rewritten to make sure 1.4 bytecode gets compiled.

By chance, have you configured anything in
/etc/java-config-2/build/compilers.conf ? By default, it should use the
lowest possible VM, but it can be configured more finely.
