I am using hibernate 3.2 and MySQL, version: 5.0.45-community-nt and mysql-connector-java-5.1.5 as mysql connector
I have nothing special in the config as such. below i have given my config file
Everything seems to be alright as far as functionality is concerned but I am suspending my debugger with any exception and I am quite frequently seeing this nullpointer exception

JdbcOdbcDriver.finalize() line: 96
Finalizer.invokeFinalizeMethod(Object) line: not available [native method]
Finalizer.runFinalizer() line: 83
Finalizer.access$100(Finalizer) line: 14
Finalizer$FinalizerThread.run() line: 160

I know the call stack is not very helpful but I have got only this and since it seems to be unrelated to my application actions at this point I don't have any idea on how to narrow down the issue..not sure it is hibernate/my set up issue or not.. will really appreciate any pointers or suggestions

Here is my hibernate config (i have omitted connection username/passwd and mapping resources)

Hey thuhouse,

I have the same problem - however, I built a sample app that uses jdbc only and left hibernate out completely and the problem persisted. What's interesting is that the exception is thrown at a strange time - I know it's in a different thread, so it's asynchronous, but it gets thrown at the same point during debugging every time... from within the TilesRequestProcessor!!! ???

Are you using tiles?

Either way, I think it's an issue with the mysql jdbc driver in conjunction with possibly tiles, and possibly eclipse.

If you figured it out, please let me know.

..yes..i am using tiles and eclipse..i still get that issue but in my production i don't see it..only in the debugger i get it..i read somewhere it is issue with mysql driver and for that user it disappeared with latest driver but i already have version later than that..so not sure..
