Sorry is this is a repeat post.  I replied to group in the St/JVM Q and A
and it never showed.  I also did this yesterday with original post and it
did not show.  Any honts on why this is happening would be appreciated.
What I posted this morning below.

If you have more questions and/or comments concerning Smalltalk/JVM please
add them to this post.
 
And a small reminder that Smalltalk Solutions will be here before you know
it.  This year we also have a Smalltalk coding contest which should be a lot
of fun. Check out www.smalltalksolutions.com for more info.

All,
 
We received many emails concerning open sourcing St/JVM.  Below you will
find answers to some of the more common questions we received.

----------------------------------
 
Q: Which dialect of Smalltalk would it support? VisualAge? VisualWorks?
 
A: Syntactically it is somewhere between VA, VW and Squeak.  It supports
some syntax that is unique to each of these. 
 
Q: Is the point of open-sourcing the project so that the Smalltalk community
would provide the code for each dialect to be compatible with Mission's
compiler?
 
A: That the Smalltalk and Java Communities would improve, integrate and
extend the existing code base 
 
Q: Do we get unboxed floats in Smalltalk/JVM?
 
A: Not currently, but you can call Java code that uses unboxed floats.
Smalltalk/JVM floats are real objects that actually understand math :-) 
 
Q: One question though: what class libraries will be available other than
the standard Smalltalk ones?
 
A: The current library is limited
 
Q: I was wondering if you have a demo or trial version of your Smalltalk to
Java JVM product?
 
A: Yes we will make the demo available first
 
Q: Sounds interesting, I'd like to know more about how the development
environment calls the java code during development.
 
A: Natively, no additional overhead for message sends 
 
Q: Does Smalltalk/JVM allow you to convert Smalltalk code into Java code?
 
A: No, the purpose of Smalltalk/JVM is to promote the use of Smalltalk, not
provide code migration.  
 
Q: My main interest now would be related to how this project would enable
Smalltalk to access Java classes and frameworks.
 
A: Native access to Java code
 
Q: In order to make it accessible you would need to release it with a
license such as Eclipse or Apache otherwise it won't get much attention.
 
A: We appreciate the suggestion; we will look at the Eclipse/Apache/LGPL
model
 
Q: Any chance this will work in J2ME? 
 
A: It produces 100% JVM compatible class files, so it should work.  We would
appreciate feedback if it does not.
 
Q: Why run Smalltalk on Java instead of running Java in the Smalltalk
environment.
 
A: There is a JVM on almost every computer (mostly free).  Eliminates single
VM supplier problem.  Leverages huge investment in the Java environment
 
Q: Why not create an Eclipse plug-in for Smalltalk/JVM?
 
A: That would be a great idea
