Google should just buy Java from Oracle, make it open source, release it under GPL license and optimize it for performance

...just like the way they did with Motorola Mobility's patents, Java is of vital importance to android and everyone knows Oracle is not doing a great job of it. With the resources and talents that Google has, they can really turn Java around and make it the beautiful OOP language that it promised to be at its inception. Java is also ridiculed with security vulnerabilities that Oracle is struggling to patch. I think Google will do a much better job of improving Java security. By making it open-source and releasing it under GPL or a similar license, it will fall more inline with the android platform. (Java is one of the only few aspects of android that are proprietary.)
