      Ubuntu 18 (64 bit), this is actually JDK 10.0.2 (could not select from drop down)

      A DESCRIPTION OF THE PROBLEM :
      I have a heap dump that reports a very weird GC root of type BoxView.

      Download heap dump (383 MB compressed, 2.4 G uncompressed): http://botcompany.de:8081/boxview.zip
      Screenshot VisualVM: http://botcompany.de/1004590/raw/1101738

      How can BoxView be a Java frame / GC root? There 300,000 AWT components inside of it too.

      Please advise.
