Subject [jira] [Commented] (LUCENE-8527) Upgrade JFlex to 1.7.0
Date Wed, 02 Jan 2019 19:09:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-8527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16732330#comment-16732330
] 

Steve Rowe commented on LUCENE-8527:
------------------------------------

bq. \[W\]ith the default skeleton, JFlex 1.7.0 generates scanners that misbehaves when given
a spoon-feeding reader (i.e. a reader that returns at least one char but fewer than the requested
number of chars) \[....\] I'll make a JFlex issue for this bug.

I created an issue: https://github.com/jflex-de/jflex/issues/538

bq. \[I\]nvocations of JFlex's Ant target inherit options used by previous invocations in
the same Ant session. I'll make a JFlex issue for this bug.

There has been an ongoing effort to fix this, see: https://github.com/jflex-de/jflex/pull/258
, likely will be included in next JFlex release.
