dev-java/java-config: No supported implementation in PYTHON_COMPAT.

[matoro]

Traceback (occurs for both currently available versions of dev-java/java-config):

Looking at the ebuilds, it appears that their PYTHON_COMPAT is wildly out of date, with the latest supported version being python3_3(!!!). The only reason that they did not fail yet is because python2_7 had not been globally removed, which occurred today.

Given that there is a more recent and maintained version in the official portage tree, shouldn't dev-java/java-config simply be removed from the overlay?
