8235211: serviceability/attach/RemovingUnixDomainSocketTest.java fails with AttachNotSupportedException: Unable to open socket file

[TheRealMDoerr]

Clean backport of JDK-8235211. Test backport is not clean. I had to integrate it manually and add the simple change JDK-8244973 because out.stderrShouldBeEmptyIgnoreVMWarnings().stderrShouldBeEmpty(); is neither correct, nor supported in 11u.

Hi Martin, shouldn't there be similar changes done for linux/aix/bsd as well in src/hotspot/os/solaris/attachListener_solaris.cpp (e.g. the "// avoid deadlock if AttachListener thread is blocked at safepoint" code). or this this for some reason not needed on Solaris ?
We have a _door_descriptor on Solaris instead of the file descriptor named _listener .

[TheRealMDoerr]

Hi Matthias,
thanks for looking into this.
Solaris is discontinued in 11.0.13 (see mail "[11u] : SAP terminates solaris sparc support." from Götz Lindenmaier). We are no longer investigating, building or testing. If anybody wants to revive SPARC, that person should probably change attachListener_solaris.cpp, too, but there's probably nobody who would do it.
