A DESCRIPTION OF THE PROBLEM :
The following is printed perhaps 2% of the time during VM startup in 2 applications that have always worked in the past and have not changed. I have now verified the problem occurs in Hello World as well. We did recently upgrade the kernel from a one that was several months old to the latest:
