APAR status

• Closed as program error.

Error description

• A Worklight adapter using XSLT processing on an IBM 1.6 or 1.7
  Java runtime may fail with the message "JVMVRFY013 class loading
  constraint violated" for org.apache.xalan classes.  The error
  message will be returned to the invoker of the adapter and will
  appear in the application server log.
  
  additional Keywords :
  adapter,xsl,foreach,jvmrfy013
  
  Worklight Versions Affected:
  5.0.6.2-IF201403101802, 6.0.0.2, 6.1.0.1
  Initial Impact:
  MEDIUM
  

Local fix

• The problem can be circumvented by doing ONE of the following:
  - Using an Oracle Java runtime.
  - Set the javax.xml.transform.TransformerFactory service
  provider for the IBM Java runtime to
  org.apache.xalan.processor.TransformerFactoryImpl. Changing this
  value may possibly impact other users of the same Java runtime.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * 1. Users are working with IBM JVM                            *
  * 2. And using specific XSL definition in an adapter, for      *
  * example using 3 and more XML nodes in single XSL loop        *
  * definition.                                                  *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * Invoking the adapter procedure gives "JVMVRFY013 class       *
  * loading constraint violated" for org.apache.xalan classes.   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * 1. Switch to Oracle JVM                                      *
  * 2. Or Use nested loops instead using 3 and more XML nodes in *
  * single XSL loop definition                                   *
  ****************************************************************
  

Problem conclusion

• The code was fixed by using internal IBM JDK implementation of
  xalan library instead 3rd party library in case IBM JVM.
