I'm curious -- did we observe a large number of allocations here? It looks to me like this is only called once-per-JDBC-connection. Perhaps this is a connection pooling scenario? We may want to optimize body of the noneMatch() call to use a case-insensitive TreeSet if this is called frequently (instead of searching linearly for each key as we're currently doing). -- This is an automated message from the Apache Git Service.
