Sun's Java implementation remains proprietary software, just as before. It doesn't come close to meeting the criteria for free software, or the similar but slightly looser criteria for open source. Its source code is
available only under an NDA.
So what did Sun actually do? It allowed more convenient redistribution of the binaries of its Java platform. With this change, GNU/Linux distros can include the non-free Sun Java platform, just as some now include the non-free nVidia driver. But they do so only at the cost of being non-free.
The Sun license has one restriction that may ironically reduce the tendency for users to accept non-free software without thinking twice: it insists that the operating system distributor get the user's explicit agreement to the license before letting the user install the code. This means the system cannot silently install Sun's Java platform without warning users they have non-free software, as some GNU/Linux systems silently install the nVidia driver.
If you look closely at Sun's announcement, you will see that it accurately represents these facts. It does not say that Sun's Java
platform is free software, or even open source. It only predicts that the platform will be "widely available" on "leading open source platforms". Available, that is, as proprietary software, on terms that deny your freedom.
Why did this non-incident generate a large and confused reaction? Perhaps because people do not read these announcements carefully. Ever since the term "open source" was coined, we have seen companies find ways to use it and their product name in the same sentence. (They don't seem to do this with "free software", though they could if
they wanted to.) The careless reader may note the two terms in proximity and falsely assume that one talks about the other.
Some believe that this non-incident represents Sun's exploratory steps towards eventually releasing its Java platform as free software.
Let's hope Sun does that some day. We would welcome that, but we should save our appreciation for the day that actually occurs. In the
mean time, the Java Trap still lies in wait for the work of programmers who don't take precautions to avoid it.
We in the GNU Project continue developing the GNU Compiler for Java and GNU Classpath; we made great progress
in the past year, so our free platform for Java is included in many major GNU/Linux distros. If you want to run Java and have freedom, please join in and help.
