I see API errors on jdt.core and SWT if using https://download.eclipse.org/eclipse/downloads/drops4/S-4.33RC2a-202409030240/ as baseline and https://download.eclipse.org/eclipse/downloads/drops4/I20240903-1200/ as IDE.

For jdt.core it complains about removed noextend/noimplement restrictions on multiple types (wrong), for SWT about changed execution environment.

Is this expected at this stage?
