reassign 798855 openjdk-7-jre 7u85-2.6.1-5
thanks

Dear OpenJDK maintainers,

It seems that #508650 (empty windows for non-reparenting window
managers) has resurfaced, the issue can be reproduced using josm and
its 'Download from OSM' menu option under awesome.

The fix for #508650 was the introduction of the
_JAVA_AWT_WM_NONREPARENTING environment variable and related handling
in openjdk-6, these changes may have been lost in openjdk-7 and later.

Is such a change possible in openjdk-7, or at least openjdk-8 which
should become default in the not to distant future?
