Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects all users of the OGSi bundles shipped as
  part of the WebSphere MQ (WMQ) Version 7 Java client.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows) +Java
  ****************************************************************
  PROBLEM SUMMARY:
  If the WMQ V7 Java client classes need to load any arbitrary
  classes (for instance, if a JMSSender has a custom Serializable
  object which is set on a JMSObjectMessage), then a
  java.lang.ClassNotFoundException was thrown because the class
  requested was not part of the OGSi bundle being used.
  

Problem conclusion

• The manifest.mf for the WebSphere MQ V7 Java client OGSi bundle:
  
  com.ibm.msg.client.osgi.jms_X.X.X.X.jar
  
  has been updated to include the following entry:
  
  DynamicImport-Package: *
  
  This allows the Java client to access classes that are not
  explicitly part of the OGSi bundle.
