IT25886: EXCEPTIONS THROWN DURING CONNECTOR INITIALIZATION LEAK MEMORY

APAR status

• Closed as program error.

Error description

• If an exception is thrown during the initialization of a
  connector then the partially constructed connector object is
  leaked. An example of this is if an exception is thrown when
  creating an MQTT Output Connector then the Resource Statistics
  publisher will leak two MQTTOutputConnector Java objects every
  time it attempts to publish statistics which can lead to Java
  heap memory exhaustion.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10 and IBM App Connect
  Enterprise v11.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  Memory may be leaked if a Common Connector Framework Connector
  throws an exception before it's initialization is complete. A
  known example occurs when the MQTT Connector is used internally
  for resource publication but the MQTT connection details are not
  correctly configured.
  

Problem conclusion

• Memory is no longer leaked when a Connector throws an exception
  before it is fully initialized.
