Public bug reported:
I have a java program that can freeze xwindows during initialization.
It takes very long time for the program to finish initialization.
During the initialization phase, my desktop does not respond. Xorg uses
100% cpu. Everything becomes ok after I kill my java program. The
version of java I am using is oracle jdk 1.8.0_112 .
