   branches/7.1.x/cache-jbosscache/src/main/java/org/teiid/cache/jboss/ExpirationAwareCache.java
Log:
TEIID-1439: When the keys are read back back expiration cache, the "expiration" key should be transparent to the user so as to not to mistake this as the actual cache key. To have a separate key is side effect of using the JBC, and should be contained here in this class.
