Steps to reproduce:
- create remote Welcome sample project
- do step into
- as soon as "green cursor" appears in the editor open Variables
- press "Show Watches inside Variables view" while Variables view is empty, please notice that Variables remains empty during pretty long period of time (~5 sec) and it looks like a regression in debugger performance

Result: NPE occurs

java.lang.NullPointerException
