Since using Google is faster compared to loading the saved Javadoc, I always read the JDK Javadoc online. There was something odd today - the favicon (what's a favicon?) looked a bit off: it's a red square with a white O in the middle.
Heading off to http://java.sun.com/ I see that the header is different. It says "ORACLE: Sun Developer Network (SDN)". So that's where the red favicon comes from !
Well, I guess it will take some getting used to. I don't really know anything about Oracle, but I really liked Sun's logo much more.
