Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You upgraded from CICS TS 4.2/Java 6 to CICS TS 5.1/Java 7 and
  now your application is failing with the following error:
  
   FATAL ERROR:  'com.ibm.xylem.types.TagType'
  
  This problem only occurs with functions that uses stylesheets.
  It seems the error was occurring during stylesheet compilation
  while parsing the XSLT itself.
  
  The original exception was a CLassNotFoundException:
  
  java.lang.ClassNotFoundException: com.ibm.xylem.types.TagType
   at java.lang.Class.forName(Class.java:219)
   at java.io.ObjectInputStream.resolveClass(ObjectInputStream.jav
      a:691)
   at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream
      .java:1681)
   at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.ja
      va:1 586)
   at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStre
      am.java:1840)
   at java.io.ObjectInputStream.readObject0(ObjectInputStream.java
      :1419)
   at java.io.ObjectInputStream.readObject(ObjectInputStream.java:
      420)
  
  The ClassNotFoundException is occurring as part of
  ObjectInputStream processing:
  
    java.io.ObjectInputStream.resolveClass(ObjectInputStream.java
  
  Specifically in this instance an object is being loaded from the
  object-stream and its class-type description has been read.  The
  local-version of this class description is being loaded when the
  failure occurs.
  
  It appears that an OSGi Classloader is not properly delegating
  to the parent loader (the JVM's System Loader) when looking for
  the class:   com/ibm/xylem/types/TagType
  
  The class is loaded as part of a serialized ObjectInputStream
  load which invokes the nearest application classloader on the
  stack (in this case:
     org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader)
  
  That code appears to call:
      org/eclipse/osgi/internal/loader/BundleLoader
  
  to perform the actual class load via the "findClass" and
  "findClassInternal" methods. These methods do not appear to ever
  delegate to another loader in memory, suggesting that either the
  implementation is designed not to delegate, or the classloader
  does not believe it has a parent.

  ****************************************************************
  An OSGI application using the javax.xml.transform API fails
  with a FATAL ERROR: 'com.ibm.xylem.types.TagType' in the JVM
  error file.  This is caused because the class TagType is not
  found by the JVM, this causes the application to fail with a
  RuntimeException.

Problem conclusion

• Router.java has been updated to ensure that classes within
  the packages com.ibm.xylem and com.ibm.xtq are found by the
  classloader.
