Bug 348441

Description David Wootton 2011-06-06 13:36:19 EDT

In testing the PTP 5.0 6/3 build I loaded the source for my HPC Toolkit plugin and started an Eclipse runtime session to test if that plugin still worked. That plugin has an option to load an executable so that it can be instrumented for performance analysis. Part of theprocessing for loading an executable is to attempt to open the source files the executable as built from. When I do this, I am getting a null pointer exception with the traceback below and the editor fails to open. This worked with PTP 5.0 source I had extracted into my workspace last week. 

The code in my plugin where I attempt to open an editor with the source code is 

IDE.openEditorOnFileStore(page, ((PTPRemoteFile) list[j]).getFileObject()); 

where getFileObject returns an IFileStore object. I looked at that object in a debugger and it looks like it has the name of a remote tools connection I am using and the components of the file's source path. 

I'm not sure if this is something my plugin is doing wrong or if this is a bug in PTP code.
