Hi All,

My j2EE application using hibernate 4.1.4 core jar and hibernate 2.0 jpa and 4.0 common annotations.
and java version is 1.6 and application server is jboss-as-7.1.1.

from the past 15 days am getting high cpu utilization , when i check the thread dump it is showing 4 threads are in infinite loop at hashmap.getentry() method.

below is the detailed thread dump stack trace.

Can somebody please help on this.

If you check the stacktrace, you won't find any Hibernate package in it. The stacktrace indicates that your JSF components are causing the issue.

What you are using is called Java EE, not J2EE since you are using JBoss 7. However, why do you use Spring Framework with a Java EE Application Server?
