This patch looks correct.

IMHO the preferred long-term fix would be backporting the following
upstream XMvn patch to maven30-xmvn, which effectively does the same
thing, but affects all packages built with Maven:

This shouldn't be a problem. First, most projects specify target
execution environment and Maven generates bytecode in this specific
version. If target is not specified then it defaults to 1.5. Secondly,
tycho is a Maven plugin - it is used only for building other packages.
