Using vertical and horizontal Composite does not work under macOS anymore

[tkg1-de]

I've written a complex program working fine for several years under macOS (Intel) and Windows as well. But after upgrading to newest Java 11 it doesn't work anymore on macOS. So I used the latest SWT 4.30 together with Java 17 (OpenJDK Runtime Environment Temurin-17.0.10+7 (build 17.0.10+7)). It doesn't work. On Windows everything is fine. On macOS the second horizontal Composite is not visible. I created a simple test class showing the problem.

This is the source code:
package main;

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.RowData;
import org.eclipse.swt.layout.RowLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Listener;
import org.eclipse.swt.widgets.Shell;

public class SimpleSWTCompositeTest {

public static void main(String[] args) {
	Display.setAppName("SimpleSWTCompositeTest");
	Display display = new Display();

	Shell shell = new Shell(display, SWT.SHELL_TRIM | SWT.CENTER);
	//shell.setSize(930, 670);

	shell.addListener(SWT.Close, new Listener() {
		public void handleEvent(Event event) {
			shell.getDisplay().dispose();
			System.exit(0);
		}
	});

	RowLayout shellLayout = new RowLayout(SWT.VERTICAL);
	shellLayout.marginTop = 7;
	shellLayout.marginBottom = 7;
	shellLayout.marginLeft = 3;
	shellLayout.marginRight = 3;
	shellLayout.spacing = 0;
	shell.setLayout(shellLayout);


	Composite headerComposite1 = new Composite(shell, SWT.NONE);
	RowLayout headerLayout1 = new RowLayout(SWT.HORIZONTAL);
	headerLayout1.marginTop = 10;
	headerLayout1.marginBottom = 10;
	headerLayout1.marginLeft = 5;
	headerLayout1.marginRight = 5;
	headerLayout1.spacing = 10;
	headerComposite1.setLayout(headerLayout1);

	Label testText11 = new Label(headerComposite1, SWT.WRAP);
	testText11.setText("Dies ist ein Test-Text! 11");
	RowData statusData11 = new RowData(203, 32);
	testText11.setLayoutData(statusData11);

	Label testText12 = new Label(headerComposite1, SWT.WRAP);
	testText12.setText("Dies ist ein Test-Text! 12");
	RowData statusData12 = new RowData(203, 32);
	testText12.setLayoutData(statusData12);


	Composite headerComposite2 = new Composite(shell, SWT.NONE);
	RowLayout headerLayout2 = new RowLayout(SWT.HORIZONTAL);
	headerLayout2.marginTop = 10;
	headerLayout2.marginBottom = 10;
	headerLayout2.marginLeft = 5;
	headerLayout2.marginRight = 5;
	headerLayout2.spacing = 10;
	headerComposite2.setLayout(headerLayout2);

	Label testText21 = new Label(headerComposite2, SWT.WRAP);
	testText21.setText("Test-Text! 21");
	RowData statusData21 = new RowData(132, 32);
	testText21.setLayoutData(statusData21);

	Label testText22 = new Label(headerComposite2, SWT.WRAP);
	testText22.setText("Test-Text! 22");
	RowData statusData22 = new RowData(132, 32);
	testText22.setLayoutData(statusData22);

	Label testText23 = new Label(headerComposite2, SWT.WRAP);
	testText23.setText("Test-Text! 23");
	RowData statusData23 = new RowData(132, 32);
	testText23.setLayoutData(statusData23);
	
	shell.setText("SimpleSWTCompositeTest");
	shell.pack();
	shell.open();

	while (!shell.isDisposed() ) {
		if (!display.readAndDispatch())
			display.sleep();
	}		
	
	display.dispose();
}

}

Most likely duplicate of #1012

Yes, it is. I tested the snippet with Temurin-17.0.10+7 and reproduced the issue. I applied #1081 and ran the snippet again and it was OK.

@tkg1-de Please can you confirm macOS version and whether you use Intel or Silicon Mac.

(A workaround is to use Temurin-17.0.9)

Yes, it seems really to be a duplicate of #1012. So closing is O.K.

I use an Intel Mac (MacBook Pro 13-inch, 2019, Two Thunderbolt 3 ports). macOS 14.3.1 (latest version at this moment)

Thanks a lot!

I use an Intel Mac...macOS 14.3.1

Thanks. I wanted to confirm this bug occurs on Intel as well as ARM.
