<https://jogamp.org/bugzilla/show_bug.cgi?id=1180>
Question remains, how did it (0 limit) happen?
Please answer in related bug report and close it if proven
to be your issue.
I guess we are a bit 'crazy' about this issue,
since iff this would be an internal bug within GlueGen and/or JOGL
it is quite substantial (and would break everything).
Hence .. we are a bit concerned and tedious now :)
