Subject [jira] Commented: (LUCENE-2074) Use a separate JFlex generated Unicode 4 by Java 5 compatible StandardTokenizer
Date Thu, 08 Apr 2010 10:10:36 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12854885#action_12854885

Shai Erera commented on LUCENE-2074:
------------------------------------

Uwe, must this be coupled with that issue? This one waits for a long time (why? for JFlex
1.5 release?) and protecting against a huge buffer allocation can be a real quick and tiny
fix. And this one also focuses on getting Unicode 5 to work, which is unrelated to the buffer
size. But the buffer size is not a critical issue either that we need to move fast with it
... so it's your call. Just thought they are two unrelated problems.

> The current trunk version of StandardTokenizerImpl was generated by Java 1.4 (according
to the warning). In Java 3.0 we switch to Java 1.5, so we should regenerate the file.
> After regeneration the Tokenizer behaves different for some characters. Because of that
we should only use the new TokenizerImpl when Version.LUCENE_30 or LUCENE_31 is used as matchVersion.
