Classpath and Kaffe
Is there any work or synchronization between Classpath and Kaffe? Are there things implemented in Classpath that aren't in Kaffe, and the same in reverse? Thanks, Duncan McQueen

Probably (I don't know what's currently implemented in Classpath). You could argue that the root of the problem is that Sun never fully spec'd the JVM, because they didn't specify what the native methods are (eg, in java.lang.Thread et.al). So Classpath and kaffe's "JVM API" are different. More to the point, they were started as separate projects, and like most separate projects, there hasn't been a lot of spontaneous communication or coordination. Plus, TVT needs to own the copyright to any files they sell to customers in the custom edition. So unless Classpath was willing to grant this right, TVT would have to rewrite everything anyway. -Archie ___ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
Re: Classpath and Kaffe
But I am concerned with the GPL Kaffe. Is it unfeasible to attempt a merge of what Classpath has done into Klasses.jar?? Duncan W.

Archie, If you thinhk that scry you should see what Sun is saying in the Sun v. M$ in court.

(at least that in the 1.1 at anyrate). Cool.. and also cool to hear about java.security.. fortunately Sun has documented the security stuff pretty well. Also, has anyone got a legal opinion of using the 1.2 spec form Sun to write an independent implementation of the 1.2 additions? I've just ordered the latest spec book from AW and I'll see what that says but I believe it's legally scary. Hmm.. I'm no lawyer, but that seems far-fetched.. you might even be able to get from Sun a letter to the effect that "It's OK to implement the Sun spec", because after all this is what they're claiming they want people to do, being "open" and all. Then if they refuse, raise hell and tell the whole world. -Archie ___ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
