[1] I created a list of differences and talked to Dan about his suggestion for the defaults. The numbers in parentheses are Dan's suggestions, but he also asked me to post here to get a wider set of opinions on these values. This list is based on the code used in infinispan-core, so I still need to go through the server code to check the default values there.

That happened when we moved away from JAXB. History: https://issues.jboss.org/browse/ISPN-1065
