Aside from leaving the JCP, is there anything more Apache could do? As long as Apache keeps contributing to the Java ecosystem through their various open source projects, Oracle still wins. As a Java developer, I really do not like what Oracle is doing, but I am not really sure of the best course of action. Should I simply boycott Java and start looking for another language? It's not that simple, for practical and economical reasons. Plus, aside from Ruby, the languages I would be most interested in run on the JVM (Scala, Clojure), and heavily depend on Java libraries. Let's say I keep using Java, and want to open source some Java code. Would it be possible to use some sort of open source license that has an exception to forbid its use by Oracle? Or would this defeat the purpose of Open Source? What if I want to contribute, but do not want to help Oracle's business?
