             Summary: Errors when selecting some JS modules in project properties [EBZ#501209]
                 Key: ERT-415
                 URL: https://issues.jboss.org/browse/ERT-415
             Project: Eclipse Release Train
          Issue Type: Task
          Components: JSDT
            Reporter: Friendly Jira Robot


AERI Report: https://redhat.ctrlflow.com/reviewers#!/problems/577453c2e4b03c6ed09af1d6

Environment:
Devstudio 10.1.0.GA

Steps to reproduce:
I was able to reliably reproduce it using these steps:
1. Have JS project in workspace.
2. Open its preferences -> JavaScript -> Modules
3. Select Lint (no error)
4. Select some other module (no error)
5. Select Lint again (error)

The same steps could be used to reproduce it with AngularJS module, Closure module and maybe some others (haven't tried them all).
