JavaFX Runs On Raspberry Pi

mikejuk writes "Oracle seem to be concerned that the Raspberry Pi manages to run Java properly and they are actively working on the problem. To prove that it more than just works, what better than to get a JavaFX app up and running — what could be more cutting edge? Unfortunately the trick was performed using a commercial version of the JDK with JIT support and some private code, but it is still early days yet. Java and JavaFX on Raspberry Pi takes us into a whole new ball game." Watch the video at the linked report to see it in action.

I think I've been reading too much Oracle/Java hate on slashdot. I misread the first sentence to mean, "Raspberry Pi manages to run Java properly. Oracle seem to be concerned and are working on the problem."

I've been reading too much Oracle/Java hate on slashdot.

Nobody really admires Oracle except for corporate CEO types. The rest of us have what equates to the same admiration for a dentist's drill. The licensing model is basically un-consentual sex. Having Oracle gunning for more IP just makes everyone uncomfortable.

Oracle have shot themselves in the foot, and this is a good example of why. Even if the R-Pi runs Java, no one is going to trust Oracle not to sue them out of existence after the way they've abused Google over its use of Java on the Android platform.

The code was. But if you want to write any Java code you need to use Java APIs. Those are copyright and subject to Oracle's terms of use. Go to http://docs.oracle.com/javase/7/docs/index.html - see that link to a copyright statement at the bottom: http://docs.oracle.com/javase/7/docs/legal/cpyr.html. That document says:

1. 1. This software ... provided under a license agreement containing restrictions on use ...
2. 2. Except as expressly permitted in your license agreement or allowed by law, you may not use, ... any part, in any form, or by any means.

So what is the license agreement: Try to download the documentation (http://www.oracle.com/technetwork/java/javase/documentation/java-se-7-doc-download-435117.html). That has a click though agreement to http://download.oracle.com/otn-pub/java/licenses/java-se-7-spec-license.txt, which in turn says:

1. License for Evaluation Purposes. Oracle hereby grants you a fully-paid, non-exclusive, non-transferable, worldwide, limited license (without the right to sublicense), under Oracle's applicable intellectual property rights to view, download, use and reproduce the Specification only for the purpose of internal evaluation. This includes (i) developing applications intended to run on an implementation of the Specification, provided that such applications do not themselves implement any portion(s) of the Specification, and (ii) discussing the Specification with any third party; and (iii) excerpting brief portions of the Specification in oral or written communications which discuss the Specification provided that such excerpts do not in the aggregate constitute a significant portion of the Specification.

So - you can use the APIs for internal evaluation only. In other words - if you wish to use them for any other purpose you need another license from Oracle.

This is exactly the case Oracle has advanced against Google (who violated clause (i) above by implementing the specification).

But, they could advance a case against any Java developer, because no matter how they learned Java, these licenses do not extend third party rights, so each developer has to officially learn about Java through the Java specifications. And if you are using Java for any purpose other than evaluation, you are in violation.

If you use something other Java SE, then you are even worse off, because the APIs are not actually published. The licenses for various versions of Java have changed slightly over the years (the one for Java 5 - which Google is being sued under - says that the license overrides all other statements from Sun, although Oracle's lawyers didn't read that far into the license else they would have used that clause to nullify the damaging testimony about Sun's approvals of Google's actions.

Before you accuse people of astroturfing, learn the turf.

If you make a Java ripoff and not be very diligent in your chinese wall cloning efforts, then you probably do have something to worry about.

Have you actually followed Oracle v. Google?

The amount of "Chinese wall" breakage is minuscule -- the rangeCheck function and a bunch of *Impl files which were only ever used in the test suite and which never made it into any shipping phone. The jury is likely to decide that this copying is de minimis, and thus excusable, and even if they don't, good luck showing substantial damages from it.

The place where Oracle is placing their stand isn't on claims that Google got their clean-room development procedures wrong, but on a claim that the APIs themselves are copyrighted, and thereby that anything built to be compatible with them necessarily infringes. That's a very different ballgame, and a much more dangerous claim.
