> In EmbedConnection.clearLOBMapping()  the code which iterates over lobFiles has a finally
block which clears the Set.  This causes a ConcurrentModificationException to be thrown and
even using a concurrent data structure would still result in only one LOBFile being correctly
closed.
> This will occur anytime the lobFiles Set contains more than 1 LOBFile.
> Stack Trace:
> java.sql.SQLException: Java exception: ': java.util.ConcurrentModificationException'.
