Strange problem when Mac is set to Dark and Eclipse theme is Light in RCP app [message #1844171]

Eclipse 4.21 RC2
macOS 11.5.2

With the following settings Eclipse correctly uses its own Light theme, even when the macOS theme is set to Dark:

- Mac Preferences, General, Appearance, Dark Theme
- Eclipse Preferences, General, Appearance, Light Theme

However, when using the same settings, our RCP application, Archi (https://www.archimatetool.com), many controls are not rendered using the Eclipse Light theme, as can be seen from the attached screenshot. We use the exact same Light theme as Eclipse itself.

If we build our RCP app against Eclipse 4.18 this problem does not occur.

Also, if I replace our RCP app's executable launcher with one from our Eclipse 4.18 based build, the problem also doesn't occur.

Running the following command for our executable launcher, "Archi" outputs "sdk 10.14", and for the older Eclipse 4.18 based version of the RCP app outputs "sdk 10.10"

otool -l Archi | grep sdk

So I think this has something to do with it.

But I don't understand how it is that this all works OK for Eclipse itself, but not for our RCP app?

Running a child Eclipse instance from Eclipse displays the same problem.

1. Set the macOS system theme to Dark
2, Launch Eclipse 4.21
3. Set the Eclipse theme to Light - all controls display correctly
4. Run/Debug a child Eclipse
5. Set the child Eclipse theme to Light - display of controls is messed up

Obviously the first Eclipse instance is spawned from the launcher executable, and the child Eclipse instance is spawned using Java (AdoptOpenJDK-11.0.11+9). But if the Eclipse executable is compiled against SDK 10.14, and also Java binary is compiled against SDK 10.14, how come the first instance of Eclipse displays correctly, but not the second? Is their something different about the Eclipse executable?

To answer my own question...

Add the following to Info.plist in the RCP app:

<key>NSRequiresAquaSystemAppearance</key>
<true/>
