Dawid Weiss commented on LUCENE-5168:
-------------------------------------
Very likely a compiler bug. It'd be best to run with tests.jvms=1, pass
-XX:+PrintCompilation -XX:+PrintAssembly (requires hsdis) and capture two logs
-- one for a failing run and one for a passing run. Then it's all about
inspecting the assembly output via diff -- this would narrow down the scope of
looking for the faulty jit optimization. Can't do it today but if anybody beats
me to it I'm interested in what you can find out! :)

> This assertion trips (sometimes from different tests), if you run the
> highlighting tests on branch_4x with r1512807.
> It reproduces about half the time, always only with 32bit + G1GC (other
> combinations do not seem to trip it, i didnt try looping or anything really
> though).
