runtime/handshake/HandshakeWalkStackTest.java failed occasionally at Linux-x64

[Guoxiong Li]

Hi all,

I accidentally found runtime/handshake/HandshakeWalkStackTest.java failed
at Linux-x64 when I tested another bug in my own branch. Then I rerun this
test and it passed which confused me.

In order to identify that my own code is right, I rerun all the tests of
the branch master instead of my own branch at Linux-x64 many  times to
reproduce the failed test.

Finally, I reproduce the failed test in branch master. The failed test log
is shown in the following link.
complete log:  https://github.com/lgxbslgx/jdk/actions/runs/379035778
concrete location:
https://github.com/lgxbslgx/jdk/runs/1442650519?check_suite_focus=true

And the passed test log is shown in the following link for you if needed.
https://github.com/lgxbslgx/jdk/actions/runs/379224900

Hope these logs could help diagnose the bug.

Best Regards.
