In current version of 6.3.0 release notes (Revision 6.3.0-17), there's a clarification needed in chapter 7.2. Enhancements in the Clustering section, regarding bug 1025023 Add configuration option to enable/disable Infinispan statistics.

The text as it stands implies that Infinispan statistics are enabled by default. This is not the case. I suggest rewording the text like this:

---
This release of EAP 6 includes an enhancement to the clustering system. The Infinispan subsystem can automatically gather usage statistics. It is possible to enable or disable statistics explicitly per cache container and per cache.

These statistics can help profile and debug applications and caches, however their use incurs a small overhead. They are disabled by default and can be enabled if needed.
