> Attached sources can generate OutOfMemoryException when ActiveMQ pulls messages by \
> using TopicSubscriber.receive(timeout), on the other hand, if I use callback \
> TopicSubscriber.onMessage(), all the messages are received without any problem. \
> Please see README.TXT for detail usage of the program. Assume I set prefetch=50, \
> publisherCount=10, subscriberCount=10, each publisher publishs 500 messages, and \
> each message size is 100kb, If I use callback (option -msgcallback given in command \
> line), e.g., TopicSubscriber.onMessage(), all 50,000 messages are received without \
> error.  if I don't use callback (option -msgcallback not given in command line), \
> e.g., TopicSubscriber.receive(timeout), after receiving about a thousand of \
> messages, OutOfMemory error occurs, and the program starts to throw Exception.
