             Summary: 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
            Priority: Minor


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.
