Comment 2 Martin Matula 2004-10-13 23:24:20 UTC 
The problem seems to be that DefaultLangModel.doFire starts MDR
transaction and then transitively tries to lock Children.MUTEX, which
is illegal. Dane, can the transaction locking be removed from
DefaultLangModel.doFire? Or does wrapping of the transaction by
Children.MUTEX (so that it is locked first) make better sense?
Comment 3 Daniel Prusa 2004-10-14 10:07:33 UTC 
I have removed mdr transaction from DefaultLangModel.doFire. This
transaction was added as a part of fix of issue 46345 and seems to be
redundant.
Emane, can you confirm that the change has not an impact on tests
(that it does not cause a deadlock in the javasrc tests on your
machines) ?

The tests seem right, no deadlock there.

Honzo, can you verify this issue, please? Thanks.
