RMIC Type Error compiling to JDK 1.4.1

["Russell T. Howard" <rhoward@xxxxxxxxxxxxxxx>]

 We are in the process of finally upgrading from WAS 5.0.x to WAS 5.1.x     
 and for the most part all of our applications work fine compiled with      
 JDK 1.3 running under JRE 1.4.2_05, which is what comes with WAS           
 5.1.x.  However, there is one problem application that behaves differently 
                                                                            
 between the 2 WAS versions.                                                
                                                                            
                                                                            
 After some fruitless debugging and a rebuild/redeploy I decided to         
 change tactics and compile the problem application under JDK 1.4.1,        
 which is what is delivered with WSAD 5.1.1.  Following all of the steps    
 in the following link I was able to migrate my workspace to take           
 advantage of the 1.4 compiler                                              
 (

 ).                                                                         
                                                                            
                                                                            
 Most of the deployment code for the EJBs could be regenerated, but a       
 few failed and I'm not sure why.  I've been unable to find any postings    
 mentioning similar rmic failures.  Here's the message that I get:
