[jira] [Commented] (CASSANDRA-10748) UTF8Validator.validate() wrong ??

["Benjamin Lerer (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-10748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15199219#comment-15199219 ] 

Benjamin Lerer commented on CASSANDRA-10748:
--------------------------------------------

{quote}In Modified UTF-8, the null character (U+0000) is encoded as {{0xC0,0x80}}.{quote}
This seems to indicate that this code is needed. I believe the problem is more that an else is missing.

> The switch-statement in {{UTF8Validator.validate()}} can never go into {{case TWO_80}} as the assignment {{state = State.TWO_80;}} in line 75 is dead.
> I assume that the {{TWO_80}} case is completely superfluous - but would like to have a 2nd opinion on this.
