Using IcedTea in GCJ

Using IcedTea in GCJ

[Marco Trudel]

Hey all

Now that IcedTea has passed the Java 1.6 compatibility test, I wonder 
what will happen to GCJ/GNU Classpath:
- Will GCJ go and directly import IcedTea?
- Will GNU Classpath slowly start to replace their components with 
IcedTea components and GCJ will keep importing GNU Classpath?
- Will GCJ/GNU Classpath die because IcedTea/OpenJDK is here? I observed 
a considerable decrease in activity at least for GCJ.

Or will everything stay as it is and GCJ won't make use of IcedTea? As 
far as I understand, GCJ supports more platforms than IcedTea/OpenJDK. 
So I guess it's a question what's more important: Quality or Quantity. 
Unless IcedTea code will be used for the main (supported) platforms and 
the rest will be kept maintaining. What seems very hard...


thanks
Marco

It's not legally possible to do that: only code assigned to the FSF may be
imported into the gcc tree.

I'm seriously considering porting gcj to the OpenJDK library.  There are
some complex GPL v2 / GPL v3 licensing issues to deal with, though.

I see... Always these law stuff... *sigh*

That would be great. But I guess it might take a while until it's ready 
(law stuff again ;-))...


Thanks for your answer

As well as the legal issues, it's also quite hard to do.
