             Summary: Hazelcast integration in TomEE
                 Key: TOMEE-1723
                 URL: https://issues.apache.org/jira/browse/TOMEE-1723
             Project: TomEE
          Issue Type: Bug
          Components: TomEE Core Server
    Affects Versions: 1.7.2
         Environment: J2EE application deployed in TomEE, using Hazelcast 
distributed executor APIs
            Reporter: Praveen 
             Fix For: 1.7.3


Tomee has Hazelcast jar in it's library. I am using TomEE1.7.2 which has  
Hazelcast 3.5 version. The application is deployed in multiple tomee instances 
and Hazelcast cluster has formed successfully. However when i tried distributed 
executor to execute the task on other JVM, the task executed successfully on 
other JVM but the control is not coming back to the source JVM. Finally the 
Future task timeouts and returns null. Other Hazelcast features (distributed 
map, cluster formation etc.) are working fine except distributed executor. I 
have used same version of Hazelcast in pom.xml with scope provided. 
Surprising behavior is - deleting the Hazelcast jar from Tomee library and 
including explicit dependency on Hazelcast jar of same version (3.5) in the 
application is working fine. Not able to comprehend this behavior.
Using latest versions of Hazelcast (3.6.1) in TomEE also didn't solve the 
issue. 
Looks like an integration issue of TomEE with Hazelcast.
 Please investigate and let us know the solution and root cause.
