Subject [jira] Commented: (LUCENE-2074) Use a separate JFlex generated Unicode 4 by Java 5 compatible StandardTokenizer
Date Tue, 17 Nov 2009 10:06:39 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12778799#action_12778799
] 

Uwe Schindler commented on LUCENE-2074:
---------------------------------------

Do we agree, that this patch should wait for 3.1, as the JFlex parser is already ok and backwards
compatible in 3.0, so no need to do anything? In 3.1 together with the other unicode changes,
we will update StandardTokenizer with Version.LUCENE_31?

> 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.
