Porting: Mac OS X Leopard

[Landon Fuller]

Given the recent discussion of porting, it was suggested I send this  
along to the discuss@ list.

I've long wondered what it would take to get the FreeBSD Java Port  
running on OS X, so this weekend I spent a couple days getting Java  
1.6 running on my x86 Leopard machine. I can report partial success  
-- hotspot compiles, the jre mostly bootstraps, and Hello World runs.  
Anything complex appears to trigger stack alignment issues (Apple's  
i386 API requires a 16-byte aligned stack)

	java version "1.6.0_03-p3"
	Java(TM) SE Runtime Environment (build 1.6.0_03-p3- 
landonf_04_nov_2007_00_06-b00)
	Java HotSpot(TM) Server VM (build 1.6.0_03-p3- 
landonf_04_nov_2007_01_30-b00, mixed mode)

	landonf at max:javasrc_1_6_jrl/control/build/bsd-i586> ./bin/java Hello
	Hello World!

Given this, it seems that getting the full JDK running on OS X (using  
X11, no Aqua) is fairly achievable. I've posted the code,  
description, etc, here:
