Depends.

I have both installed, but I have not used the 32-bit version on a 64-bit=

Some programs require the 32 bit and some come in a version for each, li=

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

that some programs, like Vuze, required the 32 bit version.


And yet they include a 64-bit JAR for the SWT part, which contains native c=

Hmm. Could you be mistaken?

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

It seems odd that you would need 2 versions of the SDK and JVM installed=

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

that seems like moving backwards.


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

One more thing occurred to me after my original post: Isn't it desirabl=

that the transition from 32 to 64 bit Java should eventually replace and=

 

obsolete the 32 bit version?


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

For instance, from the point of view of market acceptance, in light of al=

the other obstacles that exist, does it really make sense to require user=

to have installed two versions of the Java VM?


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.
