ActionUpdateThread.OLD_EDT is deprecated and going to be removed soon.

com.intellij.diagnostic.PluginException: `ActionUpdateThread.OLD_EDT` is deprecated and going to be removed soon. 'org.infernus.idea.checkstyle.actions.Close' must override `getActionUpdateThread` and chose EDT or BGT. See ActionUpdateThread javadoc. [Plugin: CheckStyle-IDEA]

I'm a plugin developer myself, the fix is pretty easy. Add

    @Override
    public @NotNull ActionUpdateThread getActionUpdateThread() {
        return ActionUpdateThread.BGT;
    }

to all action classes.

Thanks muchly - the only thing better than a clear bug report is one where you're told the fix as well 😁 Fixed in 5.88.1!
