Add “Java for Mac OS X 10.5 Update 2” to the train?

When "Java for Mac OS X 10.5 Update 1" was released I did not add it to my build train, because it was 64 bit Intel only. Now "Java for Mac OS X 10.5 Update 2" is out. It is PPC and Intel... kind of. Apple says, "This release of J2SE 5.0 and J2SE 1.4.2 supports all Intel and PowerPC-based Macs. Java SE 6 is available on 64-bit, Intel-based Macs only." I run my build train on an Intel Mac Pro. I am worried that it will also install Java SE 6. My gut say to not install it in the train, and just let software update catch it later. What does everyone think?
