I've successfully added Landon Fullers compile of OpenJDK 7 on Leopard PPC (64-bit G5) in "/usr/local//usr/local/openjdk7-macppc-2009-12-16-b4" and a "java-1.7.0" alias and executing "java -version" at least works fine.
However, I can't add the JVM to Spring Tools Suite (which is Eclipse basically). I get the dreaded "Standard VM not supported on MacOS" and no other way but Standard VM to make the correct choice.
Preferably I'd like to both run STS on openjdk7 as I'd like to use Spring Roo, which depends on JDK6 (and works with a higher version I hope). If I also need to compile the resulting source files in openjdk7 I'm not sure, but the final compile will run on Debian 5 with sun-jre6.
How can one make STS/Eclipse accept and work with openjdk7?
