Muy interesante la Reflexion de Richard Stallman sobre JAVA recomiendo leerla.

[quote=Richard_Stallman]

Sun's Java platform is not free software. You shouldn't install. If you do install it, you are putting yourself at risk of creating other problems for other people. There are people who are so attracted to java - they think this idea that will run on all platforms is so exciting - that they stop paying attention to things like what to pay attention to. They will write programs in java, they will write free programs in java and offer to people and it turns out it doesn't run on all platforms, it doesn't run on a free platform.

You see, we have free java platforms. But they don't implement all features yet. Sun keeps on adding features and our efforts are speeding up but they are still behind. So many of the java libraries or the newer language features, we don't have yet. So if you use them in your free program, it would run on a free platform and you will find that your program is actually an inducement to people to install non-free software. The same thing is happening when websites use java or websites use flash.

En otras palabras hay alternativas JAVA (JRE) que deben ser usadas ej. Classpath de lo contrario los mismos programadores de Java se verán perjudicados por depender de una Tecnología PROPIETARIA!!!
