when trying to browse that queue.

To reproduce it:

1. Start a broker with default configuration

2. Send 200k messages with

{code}ant producer -Dmax=200000 -Ddurable=true -Dsubject=TEST{code}

3. Try to browse the queue

http://localhost:8161/admin/browse.jsp?JMSDestination=TEST

The proper solution to this problem is to implement proper pagination while browsing the messages,
so users can browse through all messages showing 100 msgs (or so) at the time and not using
all the available memory.
