[oe] [meta-java] morty branch not compiling with GCC6

[Diaz de Grenu, Jose]

Hi,

Currently the compilation of openjdk7 in the morty branch with GCC 6 is failing. I noticed that the following commit in master fixes the problem:

Commit 65041a6c:  "openjdk-7: fix compile errors with current poky master (gcc6)"

Is there a reason why this has not be cherry-picked to the morty branch? Could we do that?
