There's nothing publically wrong with JDK5, unlike IE6.

Why upgrade and go through a massive QA cycle when it works? I think people have upgrade addictions these days. I still know guys using 15 year old VMS distributions.

It has full backward compatibility, but does it work?

More appropriate would have been to say that JVM 5 is the new MSVC6.

MSVC6 is the compiler that killed C++. It did not support many features from the C++98 standard. Many projects were written for MSVC6 or earlier and did not start using new language features to keep MSVC6 compatibility.

yup, that is what "backward compatibility" stands for...

No it's not.

At least it is not anymore officially supported by Sun/Oracle, and it hasn't been for quite some time.

The problem with IE6 is that it was the latest MS browser for too many years.

the point of the article is that, whether its supported or not, enterprises still continue to use it. It is similar in regards to IE 6 that MS itself has campaigns to tell enterprises to switch from IE 6 (http://www.ie6countdown.com/), but they still continue using it.

Correct me if I'm wrong, but I was under the impression that current dynamic JVM implementations had relatively similar performance to newer JVM versions, so for some that use the JVM for specialized parts of the application i.e. app engine, than wouldn't some of the changes be insignificant from a performance standpoint?

You're right, I've never heard of backward compatibility that didn't work flawlessly. I know very little of Java, but if the backward compatibility isn't perfect then I could understand why companies would be hesitant to upgrade.
