I have a somewhat curious difference between the standard command-line
java command (/usr/bin/java) which cannot do 64 bit, and the fully
path-specified one in the Java 1.5 framework which can:
marc-hazewinkels-macbook-pro-15:~ marc$ java -d64 -version
Cannot run Java in 64 bit mode. Continuing in 32 bit mode.
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)
Java HotSpot(TM) Client VM (build 1.5.0_13-119, mixed mode, sharing)
marc-hazewinkels-macbook-pro-15:~ marc$
/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/java
-d64 -version
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_13-119, mixed mode)
This is on an erase-target-disk clean install of Leopard on a 2nd
generation Macbook Pro.
