Hi ,

We are using JSF 2.1.7 and spring 3.1.1 and hibernate 4.1.4 with jboss 7.1.1 our application sometimes goes to high cpu more than 95%,
in thread dump we are seeing the below cause.
Can some one please help on this on urgent basis.

4 threads are looping on java.util.HashMap.getEntry(HashMap.java:446). If threads loop infinitely, CPU consumption will start to spike up. Looping threads stack trace are given below, examine it.
