Hi,
The obsolete PermSize=32m was removed from the wrapper script. This
should fix the error messages and start up issues with Java9. The
freezing is not related to Netbeans but to a bug in OpenJDK 7 and 8.
See http://askubuntu.com/a/691652 for a solution.
** Changed in: netbeans (Ubuntu)
Hi, this bug can be fixed as proposed in the patch
https://netbeans.org/bugzilla/show_bug.cgi?id=243569
However, NetBeans GUI freezes after a couple of minutes as described in
https://bugs.launchpad.net/ubuntu/+source/netbeans/+bug/1532634
** Bug watch added: netbeans.org/bugzilla/ #243569
