Description Phil Beauvoir

MacOS Big Sur Beta 10
Eclipse 4.17


1. Launch Eclipse
2. Select File -> Switch Workspace -> Other...
3. Click on the "Browse..." button in the "Eclipse SDK Dialog Launcher" dialog

The directory chooser dialog appears but is greyed out and it is impossible to do anything at this point except Force Quit Eclipse.

Screenshot of Eclipse greyed out

In fact Eclipse itself is greyed out at this point and no actions are possible except Force Quit.

Screenshot shows this.

Found a way out - press Escape.

The problem happens with DirectoryDialog and FileDialog created with the SWT.SHEET style and child shell as parent. If I remove this style, then the dialog opens and responds as expected. It's reproducible with a SWT snippet too.

It's strange, I was able to navigate the dialog using keyboard (Tab, arrow keys & Enter works), but doesn't respond to mouse.

SWT Snippet

SWT only snippet to reproduce the problem.

Yes, I see the same behaviour. Only with SWT.SHEET style and a child shell as parent.

Something changed in Big Sur. I'm monitoring the Big Sur beta releases and will continue to test in the hope that this might change in future Big Sur updates.

As a workaround, Eclipse/SWT can be launched with SWT.SHEET style disabled:
./Eclipse.app/Contents/MacOS/eclipse -vmargs -Dorg.eclipse.swt.sheet=false

I have good news.

MacOS Big Sur 11.0.1 beta was released today and I tested this issue. This issue is resolved.
