Fwd: RFR (S): 8022229: Intermittent test failures in sun/tools/jstatd

[Yekaterina Kantserova]

Hi,

I've done following changes after the reviews:
- added open copyrights
- documented all public functions in jdk.testlibrary.TestThread, 
jdk.testlibrary.XRun, jdk.testlibrary.ProcessThread, jdk.testlibrary.Utils
- merged jdk.testlibrary.Asserts from hotspot testlibrary

Jaroslav's comments:
- test/sun/tools/jstatd/JstatdHelper.java 82-84 - is deleted, different 
exception can show up there while waiting until jstatd is up and 
running; better just look for valid pid;
- test/sun/tools/jstatd/JstatdHelper.java clean up processes - since 
jstatd process is daemon, the "clean up" is to kill the target process. 
Please look at the changed JstatdHelper and tell me if it's still unclear.
- test/lib/testlibrary/jdk/testlibrary/Utils.java serverSocket.close() 
should be called in "finally" - fixed
