Dear md_5, I mean if you have the latest updates (i.e. apt-get update,
apt-get upgrade). I am using 15.10 from its beta version, upgrading the
packages every few days. I used to have the locking problem, but after
installing the latest updates now netbeans just crashes. If you don't
have a problem taking the risk that your netbeans might be unusable, I
would like to see if you will experience the same problem. For example
what "cat /var/log/dpkg.log | grep "\ install\ " |tail -n 10" report?

Title:
  Java 1.8.0_66 is extremely deadlock prone regarding AWT/GTK
  interaction

Status in openjdk-8 package in Ubuntu:
  Confirmed

Bug description:
  Since upgrading to Ubuntu 15.10 from Ubuntu 15.04, the various GUI
  applications that I run, including Netbeans and Minecraft have been
  suffering from dead/waitlocks which prevent them from operating
  properly. Since I have reproduced this issue these two completely
  different codebases, I am moving the bug further upstream.

  The original Netbeans bug report can be viewed here: https://netbeans.org/bugzilla/show_bug.cgi?id=256124
  Essentially, during routine interaction and calling of various AWT methods, somewhere between 8u45 (15.04) and 8u66 (15.10), something broke causing the application to hang intermittently when these methods are called.

  Some sample jstack traces are attached, the issue should be fairly
  obvious to spot.
