Noopur, please investigate.

Comment 3 Noopur Gupta

2016-06-07 08:53:44 EDT

I am not able to reproduce it with latest Neon build and the steps given in comment #0. 

Please try with
http://download.eclipse.org/eclipse/downloads/drops4/S-4.6RC4a-201606061100/

and provide exact steps with code snippet to reproduce the issue.

Comment 4 Noopur Gupta

2016-07-21 02:20:54 EDT

Closing this for now. If you can reproduce with Eclipse Neon 4.6 build, please reopen with exact steps and code snippet.
