Be aware of Java 1.6 upgrade

After I upgraded to Java 1.6 through Mac OS X Software ... I found I totally lost my previous Java 1.5 setting since all the older JDK versions are being soft-linked to the Current(1.6) but luckily this blog below helped me get back what I used to have.

64-bit Eclipse ?


64-bit Eclipse(left screenshot) on Mac OSX is still a No-Go for me, it's very CPU hogging and can't be used as an efficient development tool ... 153.2% of CPU usage for rebuilding a project seems too high for me but 32-bit Eclipse (right screenshot) scored 126.6% is not conceivable too.

I may have missed something, but should I test 64-bit Eclipse with 64-bit kernel to get a better performance number ? unfortunately Apple will not support 64 EFI for my aged MacPro 1.1 ... :( should have done my homework before I bought this 4-year-old MacPro ... well, smart people sometimes make stupid mistakes let alone a regular person like me ...
