I used to work for Oracle (They own JAVA) and I am a big open-source advocate.
Linux is the answer! Just wanted to let everyone know that there is an open-source JAVA called openjdk.java.net. This provides an alternative to the common JAVA. It has pretty much all the same features however it has a large active development community.
Try Ubuntu on Windows today. All it takes is download and run the simple installer. It is of course free, and does not modify your current Windows so you can remove it at any time without hassle.
I find Daily Paul people quite open minded, maybe you will consider looking into some of the alternative Linux systems that are available to you. If you ever need help there are many online communities and public chats available such as IRC to help you.
