Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The z/OS ProxyMBeanSupport code unregisters a Java Management
  Extension (JMX) Management Bean (MBean) when the count
  of servant regions being managed for the MBean becomes zero.
  This is incorrect for MBeans which are registered by adjunct
  region(s).

  ****************************************************************
  Java Management Extension (JMX) Management Beans (MBeans)
  registered in the z/OS adjunct region, for example, Service
  Integration Bus (SIB) MBeans, may be incorrectly unregistered
  by the Control region proxy
  com.ibm.ws390.management.ProxyMBeanSupport
  because the count of Servant regions managing the MBean is
  zero.  This may result in MBeans being unavailable.  Expanding
  Application Servers --> <server name> --> Messaging engines in
  the administrative console may display status as "unavailable."
  

Problem conclusion

• The code has been modified such that, the count of MBeans being
  managed in the adjunct region is considered before unregistering
  the MBean.
  
  APAR PK98492 is currently targeted for inclusion in Service
  Level (Fix Pack) 7.0.0.7 of WebSphere Application Server V7.0.
