BN 8.1 beta throw an exception while starting an aborts. No .netbeans/8.1beta directory, starting from a "clean session".

This warning appears in the log: Could not install look and feel [GTK look and feel - com.sun.java.swing.plaf.gtk.GTKLookAndFeel]

Later came the exception

Using OpenJDK Runtime Environment (build 1.8.0_66-internal-b01) from Debian Testing on a Debian Stretch/Sid OS.

Workaround: specify a different LaF

$ netbeans -- laf Metal

This is most probably not a NetBeans issue but reassigning to Platform for appropriate evaluation.

Comment 2 Martin Entlicher 2016-05-16 07:12:00 UTC

Looks like some GTK issue in OpenJDK.
Do not have such problems with 8.2 dev builds on JDK 8.
