The problem is indeed related to not properly closing the bdb database, and
that is triggers another problem. In BerkeleyDbCommand data is being stored
into the transaction log and been read from the transaction log later on.
Something goes wrong making the indexName being retrieved from the transaction
log look like garbage.
I think I have located the problem. In the method BerkeleyDbCommand#writeToFile
the sequence of elements written to the buffer is different from the order in
which the method BerkeleyDbCommand#readCommand reads those elements. The
BerkeleyDbCommand#writeToFile method cannot be correct, because it first writes
the indexName and then its length. It should of course first write the length
and then the indexName.
