Running series of tests on Solaris 10 (SunOS sc11136549 5.10 Generic_147441-26 i86pc i386 i86pc)
I'm getting a lot of exceptions like

sun.awt.X11.XException: Cannot write XdndAware property

We used to have such a bug, JDK-7027598, closed as not an issue after hanging in Incomplete state for some time.

Unfortunately, I cannot provide a minimal independent test as of now, and the machine itself is lent to me for GA testing only. I'm filing this bug just to raise awareness about this issue! and understand it may be fixed not earlier than jdk9.
