Julien Aymé commented on COLLECTIONS-355:
-----------------------------------------
Hello,
I think the ClassCastException is thrown because what the lstQueuedPsgrs object
you have is not an HashMap but a ListOrderedMap.
Did you try to cast your object to a Map instead?
It is generally better to use the Map interface rather than a specific
implementation in case of the implementation changes, just as the error you
appears to have.
HTH,
Regards,
Julien
