PROBLEM CONCLUSION:                                             
Removed duplicate get() calls to interceptor data cache,        
eliminating a timing window between the two calls.              
Reimplemented interceptor data cache so that its entries are    
held for the lifetime of a method's class (instead of just for  
the lifetime of the Method object itself).                      
                                                                
The fix for this APAR is currently targeted for inclusion in
