*sigh*

This looks relatively harmless, though. 
https://github.com/rkennke/jdk/commit/e5afb43cbcc1 added zapping entries and 
extra verification. This test is (again) coming from the single path that 
inspects the lock-stack of a foreign thread concurrently. When doing that, we 
cannot be sure to not observe zapped entries, because the foreign thread may 
zap as we go. It's actually surprising that we haven't seen this earlier, the 
change is more than a month old. Fix is to relax the test for this case. I 
pushed that fix, let's see if we're good now.
