I recently read an article: Twelve Disaster Scenarios Which Could Damage the Technology Industry which mentioned among other the possible "disaster scenarios" also: Oracle starts charging for the JDK, giving the following as argument:

Oracle could start requiring license fees for the JDK from everyone but desktop users who haven't uninstalled the Java plug-in for some reason. This would burn down half the Java server-side market, but allow Oracle to fully monetize its acquisitions and investments.

[...] Oracle tends to destroy markets to create products it can fully monetize. Even if you're not a Java developer, this would have a ripple effect throughout the market.

[...] I actually haven't figured out why Larry hasn't decided Java should go this route yet. Some version of this scenario is actually in my company's statement of risks.

I know guessing for the future is impossible, and speculating about that would be endless so I will try to frame my question in an objective answarable way:

Did Oracle or someone from Oracle under anonymity, make public, or hinted, leaked to the public such a possibility or the above is plain journalistic speculation? I am unable to find the answer myself with Google generating a lot of noise by searching JDK.
