Robert Muir commented on LUCENE-6239:
-------------------------------------
+1 to backport as well. If the reference size is wrong on IBM J9 it wont have a
huge impact on the ramBytesUsed of lucene's data structures, as we have all
mentioned on this issue.
Furthermore, I don't know of a configuration of J9 that actually works right
now, you will get false NPE's in normswriter when indexing, etc etc.
