Bug 30941 Preferences default initialization. Can not do a syncExec
20030204 The initialization of the preference default currently contains a final Display display= Display.getDefault(); display.syncExec(new Runnable() { public void run() { Color c= display.getSystemColor(SWT.COLOR_GRAY); rgbs[0]= c.getRGB(); c= display.getSystemColor(SWT.COLOR_LIST_FOREGROUND); rgbs[1]= c.getRGB(); c= display.getSystemColor(SWT.COLOR_LIST_BACKGROUND); rgbs[2]= c.getRGB(); } }); We should avoid and remove this as this is a candidate for a deadlock.
