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 Assignee: Victor Rubezhny Labels: General, bzira 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).
