[Sealed types][selection] Can't navigate in files in 2nd level child

[DamnClin]

Eclipse Version: 2024-06 (4.32.0) on Ubuntu

Create:

public sealed interface Top permits Middle {}
public sealed interface Middle extends Top permits Down {}
public record Down(String foo) implements Middle {}

Open Down and try ctrl + clic String: no action.

When using F3 on String:

("Problems opening an editor. Cannot read the array length because "superPermittedTypes" is null")

Will be the same for any element in this file or any file with a hierarchy looking like this one

Could you please attach the stack trace from the error log?

[iloveeclipse]

Thanks, it's jdt.core issue.

[srikanth-sankaran]

I think my recent bug fix in this area may already have fixed this. Will check.

[srikanth-sankaran]

Yes, I can confirm that this problem is already fixed on master HEAD - problem went away with the fix for https://github.com/eclipse-jdt/eclipse.jdt.core/issues/2093

I will release a regression test and close this shortly
