PermGen space size

If you intend to use Infinispan, you will have to increase the PermGen size to at least 256 Mo due to the latest versions of JGroups that are needed by Infinispan (please note that Infinspan is only dedicated to the community for now, no support will be provided). In case, you intend to use JBoss Cache, you can keep on using JGroups 2.6.13.GA which means that you don't need to increase the PermGen size.
