When a file is corrupted, the skip function can return 0, causing an infinite loop.
Here is the code:

{code:java}
  private boolean slowReadUntilMatch(Pattern markPattern, boolean includePat,
                                     DataOutputBuffer outBufOrNull) throws IOException {
      ...
      for (long skiplen = endPos; skiplen > 0; ) {
        skiplen -= bin_.skip(skiplen); 
      }
      ...
  }
{code}
