Oracle to start requiring subscription for Java

Clickbait title. Oracle charges money for commercial support. In other news water is wet.

Anyone care to explain the real benefits of this rather expensive product?

As I understand it, Oracle doesn't require it to enable anything ... is early access to new builds that important?

This is necessary because why???

There's already the regular jdk, does this add anything. Is there anything in the professional package as for useful tools?
