Hi, Here is one possible solution for the issue JDK-8028094. http://cr.openjdk.java.net/~bvaidya/8/8028094/webrev/ I am not sure pkill is available in all Unix flavor at /usr/bin directory, but it is present in Solaris and OEL 6. I have tested on Solaris and OEL and "sleep 6666" is no longer left over. Thanks Balchandra
