Re: RFR(M): JDK-8072395: LingeredAppTest.java and JMapHeapConfigTest.java fail due to LingeredApp ERROR: java.io.IOException: Lock is too old. Aborting

[Kevin Walls]

Hi Dmitry - like it, and particularly like getting shouldSAAttach() in 
both jdk and hotspot.  Yes you're very efficient in just reading that 
one byte from those one-byte files! 8-)

Sorry one more thing...  JMapHeapConfigTest.java throws an exception 
when it doesn't think it will have permission to attach - other tests I 
think that know they aren't going to work, just print a message and 
return from main, they don't count this as a failure. I'll leave that 
for you to decide!...

Thanks
Kevin

Hi Everybody,

Please review the changes:

   http://cr.openjdk.java.net/~dsamersoff/JDK-8072395/webrev.04/


1. Removed lock age test, because LingeredApp can run more than one hour
of machine time.

2. Added code to check for common environment pitfalls and produce
meaningful diagnostic

3. Testlibrary method canPtraceAttachLinux refactored, fixed yama
ptrace_scope check.

4. Sync Platfrom.java in hotspot and jdk testlibraries
