  * PROBLEM DESCRIPTION: NoClassDefFoundError for                *
  *                      com.ibm.dataaccess when running CICS    *
  *                      Java Db2 application after Db2          *
  *                      maintenance (UI47391)                   *
  ****************************************************************
  A CICS Java application that uses a Type 2 Db2 connection
  accesses data from the Db2 database.  The CICS region is
  configured to use Java 7.1 or above. Conversions occur to
  transform these into Java objects, this causes a
  NoClassDefFoundError for a class within the package
  com.ibm.dataaccess causing the application to end abnormally.
  

Problem conclusion

• Router.java has been updated to expose the com.ibm.dataacess
  package in OSGi and Liberty JVM servers.
  

Temporary fix
