0002093: Null pointer exception in Env.getConnection()
When the remote side closed a MySQL connection, the latest code was trying to recover (this is with "ping" specified in the <database-default> section of the web app's resin-web.xml). But it ended up getting a NullPointerException the next time the PHP code called mysql_connect(). The connect call then fails.

This is probably a sign of a deeper bug but the following patch fixes the immediate problem and seems like a good sanity check in any case:
