Subject [jira] Commented: (LUCENE-2399) Add support for ICU's Normalizer2
Date Sat, 17 Apr 2010 07:51:25 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12858108#action_12858108
] 

Uwe Schindler commented on LUCENE-2399:
---------------------------------------

I know, you were running the test without assertion from Eclipse! :-)

{noformat}
[junit] TokenStream implementation classes or at least their incrementToken() implementation
must be final
[junit] junit.framework.AssertionFailedError: TokenStream implementation classes or at least
their incrementToken() implementation must be final
[junit]     at org.apache.lucene.analysis.TokenStream.assertFinal(TokenStream.java:117)
{noformat}

So for me the assertion worked. The *second* patch of course works with icu-4_4.jar! So great
and I am happy about the cool interfaces at CharTermAttribute.

I just wanted to check that the my deputy sheriff did not miss something because of wrong
instructions.

LUCENE-1488,

property in Unicode).
> This is great, because it provides a ton of unicode functionality that is really needed.
