APAR status

• Closed as program error.

Error description

• When using @Inject on a method with multiple parameters on a
  Java EE component class (e.g. a Servlet or EJB class), the
  parameters might be passed to the method in the wrong order.
  
  This may either result in the parameter values being mixed
  up, or an error such as the following:
  
  CWNEN0074E: The [Ljava.lang.Object; type of the object
  instance obtained for the @Inject
  java.lang.reflect.Method.testInject(...) reference is
  incompatible with the type of the private void
  test.TestServlet.testInject(...) member.

  ****************************************************************
  When using @Inject on a method with multiple parameters on a
  Java EE component class (for example,. a Servlet or EJB class),
  the parameters might be passed to the method in the wrong
  order.
  
  This may either result in the wrong data being passed to each
  parameter, or an error such as the following:
  
  CWNEN0074E: The [Ljava.lang.Object; type of the object instance
  obtained for the @Inject
  java.lang.reflect.Method.testInject(...) reference is
  incompatible with the type of the private void
  test.TestServlet.testInject(...) member.
  

Problem conclusion

• Parameters to @Inject methods are now sorted correctly.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 8.5.5.7.  Please refer to the Recommended Updates page for
  delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• Do not use methods which are annotated with @Inject and have
  multiple parameters on a Java EE component class. Either use
  multiple methods with a single parameter, or use @Inject on a
  field instead.
