Hi,
I am using Jencks 2.2 with geronimo-connector 2.1.2 implementation. I am
using this with custom JCA RA implementation and recently when I started
this in a heavily used multi threaded environment I am getting following
exception;
java.util.ConcurrentModificationException

I looked at the source but as far as I can see we are using IdentityHashMap
but we do synchronize(pool) just before calling the matchManagedConnections
method on my connection factory.
Does anyone in the mailing encounter this....how can I solve this?
Regards
