[jboss-jira] [JBoss JIRA] Resolved: (JBCACHE-251) Cached map uses toString() of key to create FQN

Cached map uses toString() of key to create FQN ----------------------------------------------- Key: JBCACHE-251 URL: http://jira.jboss.com/jira/browse/JBCACHE-251 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 1.2.3 Reporter: twundke Assigned To: Ben Wang Fix For: 2.0.0 Time Spent: 15 minutes Remaining Estimate: 0 minutes The cached map adds values to the cache by creating a child FQN as follows: new Fqn(getFqn(), key); or, more recently, AopUtil.constructFqn(getFqn(), key); This ultimately calls toString() on the key object when the FQN is converted to a string representation. However, toString() should not have to be written to give a meaningful value to the cache in this instance. A well-written toString() will most likely produce very cache-unfriendly FQNs. A better option is to convert the key object into an internal representation using hashcode(), similar to the default Object.toString() implementation.
