Emmanuel Lecharny commented on DIRSERVER-1377:
----------------------------------------------
After some more investigations, the problem is narrowed to the JdbmTable.put(K,
V) operation, not necessarily on the oneLevelIndex (but most often on this
index).
A possible bug in JDBM ?
At this point, I see no other option than to remove all the surrounding code
and do a direct tester on the index. It will be faster to determinate what can
be the problem...

> Fix For: 1.5.5
