Hi Ranjith Gampa,
I don't disagree that you don't have a problem. Yet the title of this issue is "Memory leak in BoundedConcurrentHashMap.LIRS" - which I am not seeing any evidence for: as mentioned it's a cache and it's meant to hold on to its references - although a limited amount.

So unless we can get a reproducer to show the limit is breached by a significant amount (the LIRS algorythm doesn't enforce a strict boundary), we will reject this issue. We can of course discuss your specific problem, but separately - probably on the forums.

In particular I have the impression you have way too many SessionFactoryImpl instances (136 ?) and even multiple copies of the SessionFactoryImpl class definition. This suggests there's something wrong with your framework or with how Tomcat is setup, not a problem with Hibernate.
