yes, the good thing is that AIX has xinerama support, at least
client-side (I don't know if the native Xserver is really supporting
it but I don't think that many people are really sitting in front of
an AIX server nowadays anyway :).
The bad thing is that the xinerama support apparently never ever
really worked on AIX. I've opened "8220528: [AIX] Fix basic Xinerama
functionality" (https://bugs.openjdk.java.net/browse/JDK-8220528) for
it and will post a fix tomorrow.
Thank you and best regards,
