[linuxtools-dev] Callgraph: Strange behaviour in Profile Configuration d

[Otávio Pontes <obusatto@xxxxxxxxxxxxxxxxxx>]

Hi,
I'm doing some tests with the Callgraph plugin and I found a behaviour 
in Profile Configurations that seems odd to me.
When I right-click a project and click in 'Profile as' -> 'Function 
Callgraph', eclipse creates for me a 'Profile with SystemTap' 
configuration. When I run the Profile again using the 'Profile As' -> 
'Function Callgraph' again it will reuse the configuration it just 
created. That's fine for me.
When I go to 'Profile as' -> 'Profile Configurations' I can see the 
configuration eclipse created for me. But, if I change anything in this 
configuration, click apply and close, and then run again the 'Profile 
as' -> 'Function Callgraph', eclipse will not use the configuration I 
changed. It will create a brand new configuration with default values.

Looking at the code (SystemTapLaunchShortcut.java:179) I realized it 
checks if a configuration has only default values before using it.

I am not used to run 'Profile as' stuff, but I found this behaviour odd 
because it is different from the behaviour from 'Run as' feature. If I 
change something in the 'Run Configurations' dialog and click the 'Run 
as' option again it will reuse the configuration I just changed. It 
makes more sense to me to follow the same idea.

I didn't write a patch because I don't know if it is the desired 
behaviour for any other reason, so I'm waiting for a reply.

Thanks,
Otavio Pontes
