Is there a way to set gcbf when a java callback is executing?

When a callback defined in this manner:
JMenuItem = ...
javaObjectEDT('javax.swing.JMenuItem',strMenuName);
h_Java = handle(JMenuItem, 'CallbackProperties');
set(h_Java,'MouseReleasedCallback',Callback);
is executing, gcbf() returns empty. This causes msgbox() to misplace itself. Any way to set gcbf() on callbacks created this way?
