Ant does some pretty heavy use of reflection.  You can look at the API 
specification of java.lang.Class.getMethods() [in any recent API specification 
of Java], and you'll see what should be returned by this method.  You are 
invited to implement it, if you want...  [I thought I had already said all this 
in a previous message.]

Reflection is the responsibility of the VM, so, yes , it is a missing native 
method in SableVM.  As I said earlier, I am in my first teaching week, so don't 
count on me to implement it (and the upcoming many reflection methods in the Ant 
source code that follows the call to getMethods()) before a couple of weeks.

You are free to do it, though.  getMethod (and/or? getDeclaredMethod) is already 
implemented, and can be used as inspiration.  Source file: 
sablevm-x.y.z/src/libsablevm/java_lang_Class.c .

The type structures are defined in sablevm-x.y.z/src/libsablevm/types.h .

I know you'd like it working *now*, but *I* do not have time just *now*. :(

Have fun!
