---------------------------------
Attachment: RegexWithNullByte.java
> RegExFilter Erroneously Reconstructs RowId Containing Null Character
> --------------------------------------------------------------------
>
> Key: ACCUMULO-2083
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2083
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.5.0
> Reporter: Laura Schanno
> Assignee: John Vines
> Priority: Minor
> Attachments: RegexWithNullByte.java
>
>
> I applied a core.iterators.user.RegExFilter iterator to a BatchScanner
> iterating over Key,Value pairs where the row id of the Keys are formatted as
> "<source>\0\<sink>". RegExFilter reconstructed the row id as "<source>",
> dropping the sink half. This appears to be due to the usage of the
> String(byte bytes[], int offset, int length, Charset charset) constructor to
> reset the values of the Matcher objects in the both of the matches()
> functions. The String constructor only reconstructs a String up to the "\0"
> character.
