> The bullet points could I think be clearer:
>     -Xmx: If your OS has more available memory, consider increasing the total heap memory
available to the broker JVM. Note that the JVM will require more memory than the -Xmx value.
Thread stacks and the JMVs internal classes will consume additional memory.
>     -Xss: If you have massive numbers of threads in the Broker JVM, consider reducing
the default JVM stack size of each thread with the -Xss option.
>     By default, the ActiveMQ startup scripts start the JVM with 512mb of memory.
>     If you are running an embedded broker or in a third party container, ensure that
the hosting JVM has appropriate values for the maximum heap and stack sizes.
> The line "By default...." onwards should not be part of the -Xss bullet point as it leads
to implied referencing by the reader.
