We still haven't fixed it, but I believe we understand the issue now.
See the bug report for some additional comments on where the problem is.

Nice! I didn't know those worked already. But I am unable to try it
against gcjwebplugin since it seems to demand some sort of yahoo id.

It would be nice if some kaffe hacker could explain the relation between
these versions. Which came before the other and what is the default awt
implementation for both?

That does make sense. In the GNU Classpath gtk-peer awt implementation a
lot of work has been done to support "lightweight" components (like Free
Swing). This is less developed in the old style kaffe xlib-awt
framework. But in a couple of places we seem to forgot to check that
old-style "heavyweight" (aka plain awt components) still got the events
if the lightweights didn't handle them.

Yes, as far as I can see they are not platform specific. The mouse
events issue seems to be solved now in a generic way. See:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26641

Or we can try to get kaffe to make a new release! :)
Including at least the patch from PR26641.

Thanks for all the testing. It (and the testcases) are really helpful.
