[OJB-developers] bug in PersistenceBrokerFactoryDefaultImpl

[Georg S. <ge...@me...>]

Hi Thomas,

The releaseInstance method has to be synchronized as well, otherwise a
ConcurrentModificationException will be thrown (as happened to me) when
one thread is iterating over the brokerPool while another one is releasing
an instance (adding it to the pool). :-)

Regards

Georg
