Dawid Weiss commented on LUCENE-5168:
-------------------------------------
Just a quick update -- the problem is still there, just checked with:
1) the most recent official 1.7:
Java(TM) SE Runtime Environment (build 1.7.0_51-b13);
Java HotSpot(TM) Server VM (build 24.51-b03, mixed mode)
2) the most recent official 1.8:
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) Server VM (build 25.0-b70, mixed mode)
and they both fail on the impossible assertion.

This reproduces for me solidly on a historic version of branch 4.x:
{code}
URL:
https://svn.apache.org/repos/asf/lucene/dev/branches/branch_4x/lucene/highlighter
Revision: 1512807
{code}
But since hotspot is still broken somewhere I assume the same bug may result in
other odd surprises, even if Mike spaghettified (yes, my own invention but I
just verified and it's actually a true word
http://en.wikipedia.org/wiki/Spaghettification) the code a bit to dodge the
problem.

> This assertion trips (sometimes from different tests), if you run the

> 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).
