At last, a technical question.
Yes, it should continue to use 1.5.
In general, I think you have to explicitly ask for either 64-bit or Java 6.
When Leopard came out, there were a number of Info.plist keys that were
added to support options for running 64-bit.
At this point I was hoping to point to a URL for the release notes of Java
on Leopard where these new Info.plist keys were described, but it looks
like the just-release Update 1 overwrote it. In particular, there should
be two 10.5 Leopard release notes here:
<http://developer.apple.com/releasenotes/Java/index-date.html>
but there's only the one for Update 1 (i.e. Java 6).
Another possibility is that I'm misremembering where I read about the
Info.plist keys, and it wasn't in release notes at all. I hope someone can
correct me if I'm wrong, or the release notes if they're wrong.
In the meantime, the Update 1 release notes do say that 32-bit Java 5 will
continue to be used when 64-bit can't run. This is one of the reasons
there's a prioritized list in Java Preferences, rather than just an
exclusive selection like a radio-button group.
