> When closing an already closed
> org.apache.commons.dbcp.PoolablePreparedStatement, a SQLException is thrown when
> the isClosed() method returns true.
> This seems to violate the contract of java.sql.Statement (super interface of
> implemented PreparedStatement) whose javadoc reads " Calling the method close on
> a Statement  object that is already closed has no effect." 
> Work around exists -- when ever closing a statement, also null out.  Then,
> before closing, check that it's non-null.
