[java] OpenJDK availability for Windows OS

OpenSCG maintains OpenJDK 6 installers for 32-bit Windows and other operating systems.

To configure it, create a JAVA_HOME environment variable and set it to C:\OpenSCG\openjdk-6.0.24 or whatever is the current version. Then add %JAVA_HOME%\bin; to the beginning of your PATH environment variable.

You can edit your environment variables by contextual clicking (My) Computer, selecting Properties, clicking Advanced system settings if you’re in Windows 7, clicking the Advanced tab and then clicking Environment Variables.
