Remoting 2.5.3 is a last minute release for EAP 5.1 with a security fix, JBREM-1231 - "InvokerRegistry needs to have security checks for the setters". The security fix is the only substantive change from release 2.5.2.SP3:
Release Notes - JBoss Remoting - Version 2.5.3 (Flounder)
- [JBREM-1231] - InvokerRegistry needs to have security checks for the setters
JBREM-1233- Release 2.5.3
JBREM-1219- Update remoting guide for "generalizeSocketException" JBREM-1229- Display recreated InvokerLocator when bind address is 0.0.0.0 JBREM-1232- Assure version compatibility with earlier versions of Remoting
- Smoke test passes with 2.5.3.
- I can't run the entire test suite to completion with either 2.5.2.SP3 or 2.5.3 (a clustering test complains about a port in use), but I get essentially the same results for both releases.
