The Java Trap & Knosciences Java implementation

High Priority for a Free JAVA Implementation at FSF : High Priority Free Software Projects !

For now, the Java software on Knosciences & KnoMath rely on the Sun’s Java implementation.

We are in the JAVA Trap !

Sun’s implementation of Java is non-free.
Blackdown is also non-free; it is an adaptation of Sun’s proprietary code.
The standard Java libraries are non-free also.
We do have free implementations of Java, such as the GNU Compiler for Java (GCJ) and GNU Classpath, but they don’t support all the features yet.

Quoted from Free But Shackled – The Java Trap by Richard Stallman

None of the Java software from Knosciences works on GCJ + GNU Classpath 🙁
