Where did you get this information from? The comment you quote shows my 
reply and then you somehow (erroneously) inferring that the linker API 
is based on JNI.

The Foreign Linker API support has very little to do with JNI support. 
Of course, since some of the stuff the VM has to do to go from Java to 
native are the same, performances might not be too different (unless 
state transitions are removed, which is possible with the linker API).
