Sergey Salishev updated HARMONY-4014:
-------------------------------------

    Description: 
The attached test eats 100% of cpu time on Harmony while on RI it's 0% as it's blocked in
IO op.
This is caused by busy wait in monitor enter  when trying to inflate thin lock which is held
by thread blocked in OS from other thread.
