Subject [jira] [Commented] (LUCENE-4078) PatternReplaceCharFilter assertion error
Date Sun, 27 May 2012 08:51:24 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13284124#comment-13284124

Dawid Weiss commented on LUCENE-4078:
-------------------------------------

Thanks for the insight -- interesting.

bq. is tangential to the problem – which seems to be that the JVM lets the empty pattern
split in between chars instead of codepoints, which seems like a bug.

Absolutely. This seems like a bug to me too.
