             Summary: ByteSliceReader assert trips with 32-bit oracle 1.7.0_25 + G1GC
                 Key: LUCENE-5168
                 URL: https://issues.apache.org/jira/browse/LUCENE-5168
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Robert Muir


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).

rmuir@beast:~/workspace/branch_4x$ ant clean
rmuir@beast:~/workspace/branch_4x$ rm -rf .caches #this is important,
otherwise master seed does not work!
rmuir@beast:~/workspace/branch_4x/lucene/highlighter$ ant test
