jstack output

After I installed I rebooted and launched for the first time and the Welcome screen made it to "Turning on Modules".  I have removed ~/.netbeans and ~/.cache/.netbeans after installation and rebooted the machine prior to launching netbeans for the first time. I've attached a text file with the  "jstack -F <pid>" output.  After executing the jstack command the ide loaded correctly and everything is responsive.


Relevant information:

uname -a output:

The kernel complained and repeated the following message several times:
