Regression in 2026.1.1: `sealed, non-sealed or final modifiers expected`

[EotT123]

My build is failing with 2026.1.1, but was working with 2026.1.0

java/awt/TextArea.java:7: error: sealed, non-sealed or final modifiers expected
public class TextArea extends java.awt.TextComponent {
       ^

This extensions seems to trigger the exception:

package extensions.java.awt.TextArea;

import java.awt.*;

import manifold.ext.rt.api.Extension;
import manifold.ext.rt.api.Self;
import manifold.ext.rt.api.This;

@Extension
public class TextAreaExt {
    public static @Self TextArea editable(@This TextArea textArea, boolean editable) {
        textArea.setEditable(editable);
        return textArea;
    }
}

Thanks for the fix, @rsmckinney ! However, this doesn't fix everything. It seems that another part is still broken (which I didn't identified before) (also a regression):

@Extension
public class TextAreaExt {
 // can be empty, or some extensions
}

@Extension
public class TextComponentExt {

    public static @Self TextComponent editable(@This TextComponent textComponent, boolean editable) {
        textComponent.setEditable(editable);
        return textComponent;
    }
}

Probably caused by the fact that TextArea extends TextComponent? TextArea is non-sealed, TextComponent is sealed.

In the above example, if the empty TextAreaExt extension class is removed, compilation works fine.

Have you tried using 2026.1.2?

[EotT123]

Yes. The first issue is resolved, the second isn't.

[rsmckinney]

I can repro this with 2026.1.1, but not with 2026.1.2. Did you directly integrate the change I made for this issue? A new release with this fix will be available some time tomorrow.

[EotT123]

I'm sorry, I was testing with 2026.1.2, but apparently, the latest version is 2026.1.3. With 2026.1.3, it is working fine. Thanks!

[rsmckinney]

No problem. There isn't an official tag for 2026.1.3, but there is one now for 2026.1.4.
