NullPointerException after closing the Recommendations View #121

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Open the Recommendations View and a Java file.
2. Close the Recommendations View.
3. Select a method in the Java file.

What is the expected output? What do you see instead?
I expect to see a cleared Recommendations View, but a NullPointerException 
occurs (see stack trace below).
