Depends.

I have both installed, but I have not used the 32-bit version on a 64-bit 
computer in years.

Which ones require the 32-bit version? No Java program, for sure.

And yet they include a 64-bit JAR for the SWT part, which contains native code.
Hmm. Could you be mistaken?

There's nothing in the Vuze documentation that limits it to using 32-bit Java.

Especially since you don't.

They're equally compatible. Java bytecode doesn't change for 64-bit vs. 32-bit.

The operative word being "seems" since the premise is false.

No, since one doesn't render the other obsolete.

No, but then no one does.

What other obstacles? Java is arguably the most widely accepted programming 
language right now. Certainly it's up there.

Facts not in evidence, premise of the question not valid, there is no 
meaningful answer.
