PH60859: ARRAYOUTOFBOUNDSEXCEPTION WHILST USING THE JCICS KSDS CLASS AS A BEAN IN SPRING BOOT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An application that uses Spring Boot in CICS Liberty is using
  the KSDS class from the JCICS library. The Bean creating the
  class instance uses the @RequestScoped annotation.
  
  After updating CICS from 5.6 to 6.1 the application no longer
  starts and the following exception is thrown :
  
  java.lang.ArrayIndexOutOfBoundsException: Array index out of
  range: 0
   at org.springframework.cglib.core.CodeEmitter.load_arg
   (CodeEmitter.java:374)
   at org.springframework.cglib.proxy.Enhancer$6.
   emitLoadArgsAndInvoke(Enhancer.java:1280)

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: ArrayIndexOutOfBoundsException from the *
  *                      Spring framework CodeEmitter.load_arg   *
  *                      method at application initialization.   *
  ****************************************************************
  A Spring Boot application is deployed to a Liberty JVM server.
  The application uses the JCICS KSDS class as a @Resource with a
  method that returns a new KSDS annotated with @RequestScope and
  @Bean.
  
  Upon startup the following exception occurs:
  
  org.springframework.beans.factory.BeanCreationException
  
  This was caused by a:
  
  org.springframework.aop.framework.AopConfigException
  
  Which was caused by a java.lang.ArrayIndexOutOfBoundsException
  in the org.springframework.cglib.core.CodeEmitter.load_arg
  method.
  
  The problem could also occur if the KeyedFile, ESDS or RRDS
  classes are used rather than KSDS.  These three classes all
  extend a non-public class File which contains method unlock().
  KeyedFile, ESDS, KSDS and RRDS do not override unlock().
  

Problem conclusion

• CICS has been updated so that JVM server entry/exit trace is not
  injected into the compiler generated unlock() method added to
  KeyedFile, KSDS, ESDS and RRDS.  This prevents the
  ArrayIndexOutOfBoundsException from the Spring Framework code.
