FYI while in this state, I enabled two features of the connection pool and tested them one at a time, but still get the "Timer already canceled" error.
1) On any failure: Close All Connections (checked)
2) Connection validation: Required (checked)
I'm not sure what's left to try other than looking in the GlassFish source code.
