PrefetchSize not working as expected

Hi all,

we're experiencing some unexpected behavior in ActiveMQ 5.7.0.1 regarding
the PrefetchSize. When a client connects to the message queue, all messages
are pushed immediately to the client. However, the default is set to 1 in
our case, since we've patched the ../transport/stomp/ProtocolConverter.java
in order to get around a known bug. This bugfix works, but the expected
behavior of AcitveMQ, only pushing one message at a time, is not what we're
currently seeing. Am I missing something? Do we still need to modify the
configuration file? Do we need to set another parameter? Is there another
bug that we're not aware of? 

Thanks in advance!

do you have a quick test case?
post your configs broker/clients and might as well post your patch too.
