Indeed I didn't update my workspace. Fixed.

Now I get another error when the native method

[Thread "main" --> JNI: java.net.PlainSocketImpl.initProto()]

is executed:

unimplemented (JVM_GetSockName in ../../../substrate/jvm.c:1948)

As I have seen in some of the talks about Maxine, you run TCK and other
kinds of tests internally on Maxine. Do you have a list that shows which
functionality from Java's class library is not usable because specific
JVM_* methods are missing? I guess that would be at least everything
which uses native methods that contain calls to back to the JVM
interface like in my socket example.

I found this posts http://tinyurl.com/yf8v7jw and
http://tinyurl.com/yc7cgu3 that explain nicely how different open source
VMs (and class libraries) implement and use the JVM interface. Is there
some similar documentation available for Maxine?  

I also would like to know if there exist documentation on the schemes
which make Maxine modular as you mention in Maxine's FAQ. I want to get
an idea of how I can use the schemes to plug in something else.

I am working on Linux systems.
