On a recent PSR testing, we saw frequent OOME on accessing the site. Later, on investigation heap dump,we found that there are large number of objects getting created for org.jboss.invocation.interceptor[] from WeavedInterceptor and ChainedInterceptor.
Below is the screen shot of it..
Later on investigation, we found its because of the bug in JBOSS7.1.1-Final, this is due migrating EJB2.1 CMP EntityBeans to this JBOSS7.1.1-Final version.
We are hitting the bug https://issues.jboss.org/browse/AS7-4675
More details on actual stack trace can be found in https://community.jboss.org/thread/198920
The patch for this issue could be found in
https://source.jboss.org/viewrep/JBossAS/cmp/src/main/java/org/jboss/as/cmp/jdbc/JDBCStoreManager.java?r1=
22dd690a56844ae54d6be29ca39014136b958566&r2=d84f915669619424fc4a4c69993fad2e128bc73b
We need to patch JDBCStoreManager.java for this in the jboss AS 7.1.1.
