IT24135: File InputStream acquired by the MQ resource adapter is never closed

APAR status

• Closed as program error.

Error description

• A number of Java InputStream objects for files are acquired by
  the MQ JCA resource adapter (MQ-RA) when it is first initialised
  that are not explicitly closed programmatically.  As a result,
  when the MQ-RA is running within GlassFish application server
  and the server is shutdown, the following warning message is
  logged:
  
  [WARNING]

  nnectors.service]

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of the:
  
    - MQ classes for JMS
    - MQ classes for Java
    - MQ JCA resource adapter
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A component known as "CommonServices" is initialised when the MQ
  classes for JMS or classes for Java are first used by an
  application, or the MQ JCA resource adapter is initialised by an
  application server.  The CommonServices component attempts to
  discover all of the individual client components that are
  available within the environment.  For example, the classes for
  Java API, classes for JMS API and Java MQI are all components
  within the MQ Java client.
  
  In order to discover the components, one mechanism used by the
  CommonServices component is to search for files named
  "compinfo.properties" within the META-INF directory of the MQ
  Java client component jar files.
  
  The CommonServices component opened an InputStream to the found
  compinfo.properties files to read the data. The InputStream was
  not explicitly closed.  This resulted in a warning log message
  when the MQ resource adapter was running within a Glassfish
  application server environment and the server was shutdown.
  

Problem conclusion

• The CommonServices component has been updated to explicitly call
  the close() method on InputStreams that are opened when reading
  compinfo.properties files included within the MQ Java client jar
  files.
