I cannot provide any code, as this is a costumer application.  But here is
something interesting (constumer package name replaced with XXX):

Found one Java-level deadlock:
=============================
"AWT-EventQueue-0":
  waiting to lock monitor 0x0000000000689390 (object 0x00002aaab433cd60, a
java.awt.Component$AWTTreeLock),
  which is held by "main"
"main":
  waiting to lock monitor 0x000000000068a2a8 (object 0x00002aaad499e610, a
XXX.applet.MenuBarPanel),
  which is held by "AWT-EventQueue-0"
