Memory leak Issue ConcurrentReferenceHashMap class of jboss7

[dattu]

We have our spring based web application running in Jboss server. Recently we came across memory issue in our application. When we check with Memory Analyzer tool we came to know that the class org.jboss.as.web.deployment.ConcurrentReferenceHashMap as one of the memory leak suspect. We checked with few of the heap dumps Eclipse MAT consistently shows this class occupying more memory.  Please can you let us know if anyone came across the similar kind of issue and aware of fix details? 

Here are the environment details,

Server: Jboss 7.0

Java Version: JDK1.7.0_10

Any help would be appreciated.

Do you use an AS7.0.x version?

As this is a real old one I recommend to upgrade to a new 7.2 (you can use EAP6.1.0.Alpha) or the current WildFly.

There are many bugfixes and enhancements and I suppose this issue will be fixed also.
