Description Martin Coufal CLA 2021-03-31 03:35:55 EDT 
When using the context menu of a file (e.g. Foo.java) 'Open With' > 'Other...' and checkbox "Use it for all '*.java' files", the setting is not remembered and all Java files are opened in the default editor, instead of the chosen one.

How to reproduce:
1. create a new Java project
2. create 2 new classes 'Foo.java' and 'Boo.java', close all editors
3. in Package Explorer, right-click 'Foo.java' and select 'Open With' > 'Other...'
4. instead of default editor, select different one (e.g. Text Editor)
5. make sure checkbox 'Use it for all *.java files' is checked
6. click 'OK'
7. double-click 'Boo.java' to open the editor

The default editor instead of editor selected for all *.java files is opened. No file type association was added to 'Preferences' > 'General' > 'Editors' > 'File Associations'.
