svn commit: r1593505 - in /directory/mavibot/branches/with-txns/mavibot/src:
main/java/org/apache/directory/mavibot/btree/
main/java/org/apache/directory/mavibot/btree/serializer/
test/java/org/apache/directory/mavibot/btree/serializer/
Author: elecharny

New Revision: 1593505
URL: http://svn.apache.org/r1593505
Log:
o Fixed the CPB generation and check.
o Fixed the LongArraySerializer to fix the CPB storage
There is still a pb with the LongArraySerializer, which is not symetric, due to the way we serialize values... It has to be fixed
