Can JBoss Cache be used with JBoss EAP 6/7?

Issue

• Can we use JBoss Cache with EAP 6? What about EAP 7?
• We are migrating from EAP 4.x (or 5.x) and do not see the JBoss Cache related libraries.
• We are upgrading our applications from JBoss 4.2 to JBoss 7.2. Where to find an alternative to replace an existing caching approach?
• We are having an issue with our applications that were upgraded from JBoss EAP 5 to JBoss EAP 7.0.

• Looking for a replacement for org.jboss.cache.Cache JBoss EAP 5.1
• Our legacy EAP 5 code uses classes org.jboss.cache.Cache to implement a cache. The legacy code uses classes from EAP 5 jars jboss-j2se.jar and jbosscache.jar. These jars and classes are not available in EAP 7. Is there a natural replacement for this in EAP 7?
