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
