[gentoo-dev] [PATCH] java-pkg-simple.eclass: allow JAVA_MAIN_CLASS _and_ MANIFEST.MF

[Volkmar W. Pogatzki]

The eclass did not handle JAVA_MAIN_CLASS if there was also a given
META-INF/MANIFEST.MF.
This change allows adding JAVA_AUTOMATIC_MODULE_NAME and/or
JAVA_MAIN_CLASS to the MANIFEST.MF file if it exists or creates one if
not.
