Setup script (destructive, run with caution!)

In some specific cases, I am unable to open files with double-click and/or F3 keypress. The key for invoking the error seems to be that you have to click on the tree item, wait for a second and then try to open the file with double-click/F3 key.

Steps to reproduce:
A) unable to open with double click or F3
1. run Eclipse, create new Java project
2. open Project Explorer, expand path to some file in JRE System Library
 - I used JavaSE-1.8: resources.jar --> com.sun.corba.se.impl.logging (but works on all types of files that I have found in JRE)
3. select 'LogStrings.properties', wait a second, select again and try to open with double click or F3
4. no editor is opened

B) unable to open with F3
1. run Eclipse, create new Java project with new file test.txt
2. close opened test.txt editor
3. select 'test.txt' in Project Explorer, wait a second, select again and try to open with F3
4. no editor is opened

Notes:
* reproducible 100%
* I am able to open all files with context menu --> Open
* no messages/errors in workspace log
* works fine in Package Explorer
