I don't believe there ever was a PPC port, but what you used was actually an early version of the "zero" architecture support. >> Is there any possibility to obtain the PPC code for that VM? > > I suspect the version of Hotspot in the BSD port is old, which is why > Zero is not compiling. Actually, the BSD HotSpot is merged up to the very latest JDK7 HotSpot. I know, because the macosx-port derives from the bsd-port, so that BSD/Mac integration issues at the HotSpot level are handled for us. Has anyone actually tried compiling the latest bsd-port with arch=zero on a PPC Mac? > Even when you get it to compile, the performance may be poor, as Zero > is just an interpreter.

While the bsd-port may be compilable for PPC with Zero and Shark, it's native graphics support will likely remain at the Darwin/X11 level. This may or may not be an issue for your use. AFAIK, nobody has come forward to make new builds of the BSD port for PPC/Mac using Zero, since it was fully integrated into the JDK7 mainline. Any volunteers?
