The bug is reproducible under Win32 and Solaris.
|
|
Setting 'null' and "" as a label of menu item
|
|
should set blank label on all platforms according to the specification.
|
|
But under Solaris setting "" as a label of menu item used to
|
|
cause some garbage to be set as label.
|
|
Under Win32 setting 'null' as a label used to result in
|
|
throwing NullPointerException.

it passes.""";
