RFR[XS] (10) 8181860 [TESTBUG] serviceability/tmtools/jstack/utils/DefaultFormat.java does not recognize "sleeping" state

[Ioi Lam]

https://bugs.openjdk.java.net/browse/JDK-8181860

This failure has shown up in the past few months with hotspot tier 2
testing. Apparently "sleeping" has been a valid state for a long time
so I don't know why the failure showed up only recently.

FYI, I ran some casual testing and the tests failed on linux/x64 but not
windows/x64.
