2. Open any Java source file.
3. Hover over a Java class or method from the base class library like String to show its javadoc
4. The UI hangs and a few second later it crashes.

Before the crash this is show on stderr:

(Eclipse:26511): Gdk-CRITICAL **: 12:06:11.663: gdk_window_create_gl_context: assertion 'GDK_IS_WINDOW (window)' failed

Expected behavior

A Javadoc tooltip is shown.

• • [x] Linux
• • [ ] macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)
