Today's Big News: Sun to release Java under the GPLv2

The internet is abuzz today about Sun's announcement to release Java to the open source community.  So what does this mean?  Is it an admission from Sun that Java is a dying technology and this is a ploy to get developers re-enthused about working with Java again?

"Sun is hoping that this step will attract more developers, as well as extend the lifespan of Java." -Slashdot.

It'll be interesting to see how this works out for them as this may force other companies like Microsoft to open up more of their source in an attempt to drive participation from the developer community.  Isn't that why Ruby on Rails is the hot language?  Will we see Java on Rails in the near future?
