        AOT captures VM settings during compilation. For compressed oops it presents a problem for the case when VM selects a zero-shift mode (that depends on being able to map the heap into the lower 4G). Compiling AOT binary with zero-shift limits it's usability. The AOT compiler should be able to avoid zero-shift.
