Photoshop CS6 does not use or require Java in any way. Nor do the CS6 installers.
But Apple "helpfully" marked the Adobe CS6 installers as using Java, even though they don't. So MacOS warns you about Java, tries to download and install Java, for nothing. Apple has promised to update their code, one of these days.
Ah, good to know. Yes, I'm on running the latest version of Lion.
So from Adobe's perspective, do you download Java, then can you remove it if it's not necessary for CS6? If so, would you know what Java file to look for to remove? (I know Lion installs other framework files for Java, which I don't want to mess with deleting at all.)
...or does it not get installed in this process, and this is all a runaround?
Yes, you can remove it --- again, we don't need it at all.
And no, I don't know what Apple installs or how to remove it.
