[7u40] Request for phase 2 approval for 8020504: Intermittent java.io.IOException: Bad file number during HotSpotVirtualMachine.executeCommand

[Peter Allwin]

Hello!

 

I'm requesting approval to push this change into 7u40.

 

It addresses an issue in the attach mechanism which causes intermittent
failures due to stale .java_pid files being left in the temp directory.

 

The change is identical from JDK8, with the following exceptions:

-          NOT_SERVICES_RETURN macro has been removed from
attachListener.hpp (not used in JDK7)

-          testlibrary/Platform.java file has been added (a jtreg
testlibrary utility class)

 

JPRT has been run with a specific regression test for this issue.
