ShutdownComplete will countdown in the finally block when thread shutdown due to an error, and in this case thread is not running.
So isRunning logic should check isShutdownInitiated and isShutdownComplete.

More detailed description of your change,
if necessary. The PR title and PR message become
the squashed commit message, so use a separate
comment to ping reviewers.

Summary of testing strategy (including rationale)
for the feature or bug fix. Unit and/or integration
tests are expected for any behaviour change and
system tests should be considered for larger changes.

@guozhangwang @ijuma @junrao PTAL, thanks

[guozhangwang]

test this please

@lushilin could we also augment the test under ShutdownableThreadTest to verify that isRunning is false and isThreadFailed is true before calling thread.shutdown and then becomes false after calling thread.shutdown.

[guozhangwang]

test this please

Also could you run the unit test suite locally (you can see README.md for instructions), the jenkins failures seem relevant.

ok,i will write test case and run unit test locally
