FWIW -- jboolean is actually defined by the platform's JNI
implementation.  Both g++ and gcj have to agree, but they also must
agree with other VMs on the platform.  This is true because JNI is
intended to be binary compatible across VMs, and because libgcj uses
the same types for CNI and JNI.

I don't know how jboolean is defined on Darwin.  Perhaps someone with
this platform and the Sun VM could say.
