Package: openjdk-6-jre
Version: 6b11-9
Severity: important
Tags: patch
It is an long standing bug that java programs come with empty gray
windows when run in non-reparenting window managers.
(For example compare http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6509038)
The old workaround was to export AWT_TOOLKIT=MToolkit, which no longer
is available (compare http://bugs.debian.org/504524), so until this is
fixed properly, it needs a new workaround.
The attached patch allows an other workaround by fixing java's behaviour
when the new environment variable _JAVA_AWT_WM_NONREPARENTING is set.
Given the large number of window managers with this problem, I'd rather
see this the default and workarounds only for known-buggy window
managers, but I guess it is too late for this in the release.
This is why the patch keeps the buggy default behaviour and only fixes
it when the environment variable is set (as without any variable, it also
did not work in etch, so it is not that big a regression).
openjre maintainers, release team, any opinions on that?
Hochachtungsvoll,
Bernhard R. Link
