Change prefetch size limit for topics from 32766 to 32767
---------------------------------------------------------

                 Key: AMQ-3242
                 URL: https://issues.apache.org/jira/browse/AMQ-3242
             Project: ActiveMQ
          Issue Type: Improvement
            Reporter: Robert Liguori


The default prefetch size limit for topics is noted as 32766; http://activemq.apache.org/performance-tuning.html

The FUSE source documentation (http://fusesource.com/docs/broker/5.4/tuning/index.html) states,
"Default prefetch limit is 32766. The default limit of 32766 is the largest value of a short
and is the maximum possible value of the prefetch limit.".

The largest value for a short actually is 32767 (http://java.sun.com/docs/books/jls/second_edition/html/typesValues.doc.html).

This is really a trivial issue, but should the default prefetch limit for topics be changed
from 32766 to 32767 to reflect the actual ceiling?
