JFace Wizard snippet crashes application and displays crash reporter in incorrect position

[agustinschilling]

Description

A simple SWT/JFace snippet was created to reproduce and investigate a potential issue related to the wizard implementation.

The snippet contains a single button (Open Wizard) that opens a JFace wizard. When the button is clicked, the application crashes and the crash reporter is displayed.

Two issues were observed:

1. Application crash when opening the wizard

   • Clicking the Open Wizard button causes the application to fail.
   • The underlying cause has not yet been investigated.

2. Crash reporter positioning

   • After the crash occurs, the crash reporter is displayed.
   • The crash reporter window appears in an incorrect position on the screen.
   • Its placement should be reviewed and adjusted.

Expected Behavior

• The wizard should open successfully without causing the application to crash.
• If an unexpected error occurs, the crash reporter should appear in the correct screen position.

Actual Behavior

• The application crashes when opening the wizard.
• The crash reporter is displayed, but its position is incorrect.

Reproduction

1. Launch the attached snippet.
2. Click the Open Wizard button.
3. Observe the application crash and the crash reporter behavior.
