      The org.apache.el.util.concurrentcache class did not synchronize requests for concurrent access to WeakHashMap. In some cases, this caused an infinite loop, which consumed excessive CPU memory. The underlying issue has now been resolved and access to WeakHashMap in the org.jboss.el.util.concurrentcache class is now synchronized.

      Concurrent access to WeakHashmap by org.jboss.el.util.ConcurrentCache causes High CPU.
      This issue is similar to https://issues.jboss.org/browse/JBWEB-185 because they use the same codebase.
