Subject [jira] Created: (LUCENE-2627) MMapDirectory chunking is buggy

MMapDirectory chunking is buggy
-------------------------------

                 Key: LUCENE-2627
                 URL: https://issues.apache.org/jira/browse/LUCENE-2627
             Project: Lucene - Java
          Issue Type: Bug
          Components: Store
            Reporter: Robert Muir


MMapDirectory uses chunking with MultiMMapIndexInput.
 
Because Java's ByteBuffer uses an int to address the
values, it's necessary to access a file >
Integer.MAX_VALUE in size using multiple byte buffers.

But i noticed from the clover report the entire MultiMMapIndexInput class is completely untested:
no surprise since all tests make tiny indexes.
