Openfire/src/java/org/jivesoftware/database/DefaultConnectionProvider.java
has the maximum active time set to 15 minutes. This is not working, and the proxool housekeeping service disconnects the thread after 5 minutes (default timeout per docs).

There appears to be a typo in setting the property
settings.setProperty("proxool.maximum-activetime", Integer.toString(activeTimeout));

per http://proxool.sourceforge.net/properties.html
it looks like it should be
settings.setProperty("proxool.maximum-active-time", Integer.toString(activeTimeout));
