Description Angel Vera 2010-10-07 11:06:37 EDT

+++ This bug was initially created as a clone of Bug #309781 +++

The following stacktrace is reported. The issue is caused by the fact that during the isCancelled, separate event loop is launched, and DebugPlugin tries to save modified editor again. 

Reproduction steps are for Eclipse based product, but they give pretty good insight into the situation:
1. Start WAS in Debug mode from RAD                                     
                                                                        
                                                                        
2. Develop a Dynamic Web project v 2.5 targeting WAS 7                  
                                                                        
3. Add a Servlet with a sysout in doGet                                 
                                                                        
4. Add the project to WAS                                               
                                                                        
5. Add a breakpoint inside doGet                                        
                                                                        
6. Debug the servlet so that it reaches the breakpoint                  
                                                                        
7. Click on the "bug" button in the debug view to restart the server in 
debug mode                                                              
                                                                        
7. while the server is restarting, add a new space char inside the doGet
method of the servlet.                                                  
                                                                        
If you do this while the server is still shutting down, then you can    
save the servlet.                                                       
                                                                        
If you wait until when the server has initiated the restart, then you   
cannot save the servlet.                                                
                                                                        
You see a progress dialog with three entries:                           
                                                                        
- Restarting WAS 7.0 server                                             
- Save                                                                  
- Starting WAS 7.0 server                                               
                                                                        
8. If you wait for some time (minutes) then you will get a dialog asking
if you want to save. Click OK                                           
                                                                        
9. Now RAD is still hanging, and you see in the progress dialog:        
                                                                        
Save                                                                    
Starting WAS                                                            
Building prerequisite project list                                      
                                                                        
However the server appears to be in started state.
