Can you please explain what this problem was? 
What do you do in order to cause the problem before you fixed it?

To reproduce the problem:
1. import a pure remote project from server. 
2. index this project. 
3. right click on a method/function to invoke call hierarchy, which is shown in remote call hierarchy view.
4. delete the project, and do not close the remote call hierarchy view.
5. double click on the method/function in the remote call hierarchy view.
6. the file in cache will be opened with an NPE message.

Expected:
step 6: file is opened without any error message.
