Christian Moen commented on LUCENE-3897:
----------------------------------------
Robert, your change to LUCENE-3895 is very useful. Thanks again for this.
I can reproduce a failing case on {{trunk}} on my system using
{noformat}
ant test -Dtestcase=TestKuromojiTokenizer -Dtestmethod=testRandomHugeStrings
-Dtests.seed=-42f0565412819c1e:75f7606c1595bc3f:-31754ca508d64340
-Dargs="-Dfile.encoding=MacRoman"
{noformat}
and the output is as follows:
{noformat}
