In last build Version: 2020-09 (4.17), Build id: I20200823-1800 can't launch eclipse 4 RCP application.

Steps to reproduce

2. Select Rich Client Application. All settings have default values.
3. Select Eclipse 4 RCP application
4. Check “Create sample content” and “Add life cycles class”
5. Open product configuration editor
6. Select “Configuration” tab. 
7. Press “Add recommended…” in “Start Levels” section. Start levels for 5 plugins  are set.
8. Select product file in Project Explorer and select "Run As... Eclipse Application" from popup menu. Got error "Error: Could not find or load main class org.eclipse.equinox.launcher.Main
Caused by: java.lang.ClassNotFoundException: org.eclipse.equinox.launcher.Main
"

The same actions under previous version start working application.

Can you mention which version of eclipse this scenario worked? Is it 4.16 GA candidate? Does this work on 4.17M1 or 4.17M2?
