IT33058: ABEND IN BIPBROKER DUE TO UNCAUGHT C++ EXCEPTION WHEN REST APIV1GENERATES A LIST OF EGS IN A RESPONSE

APAR status

• Closed as program error.

Error description

• An exception can be thrown when the admin REST APIv1 generates
  a response that includes a shallow list of the deployed
  execution groups. This exception is not caught between between
  C++ and the JNI leading to an abend with the following native
  stack:

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10 using the REST Admin API
  v1.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  An exception can be thrown when the admin REST APIv1 generates a
  response that includes a shallow list of the deployed execution
  groups. This exception is not caught between between C++ and the
  JNI leading to an abend with the following native stack:
  
  #1 std::terminate
  #2 ???
  #3 ImbRecoverableException::throwThis
  #4 ImbDelpoyManagerCache::processWebByPassRequest
  #5
  Java_com_ibm_broker_config_webadmin_WebAdminBrokerProxy__1proces
  sWebByPassRequest
  
  and the following corresponding Java stack:
  
  Thread 12c12c828 (current thread), name =
  "http-bio-1420-exec-1138", daemon = true, priority = 5, state =
  [alive, runnable]:
  #0
  com.ibm.broker.config.webadmin.WebAdminBrokerProxy._processWebBy
  PassRequest(String, String, String)
  #1
  com.ibm.broker.config.webadmin.WebAdminBrokerProxy.processWebByP
  assRequest(WebAdminBrokerProxy.webBypassRequestType, String)
  #2
  com.ibm.broker.admin.responseObject.container.ImbEgContainerBean
  .<init>(ImbURI, WebAdminBrokerProxy, ImbURI, int)
  #3
  com.ibm.broker.admin.requestHandlers.DeployedObjectsRequestHandl
  er.getEGs(int)
  

Problem conclusion

• The product now correctly handles transferring this exception
  from the C++ layer to the JVM and returns an REST API v1 error
  response.
