Yeah, gcj is a Java front end for the gcc compiler: Java goes in, native
code comes out. It compiles from either Java source or classfiles; it
doesn't recognize all current source constructs (like embedded classes),
so classfiles are usually a better choice.
gcj is a full-native solution, it cannot load or interpret classfiles
(although they're working on it). As for debugging... it's like any
other native language. The executable includes tables that map code
addresses to source line numbers, so debuggers like gdb can do
source-level debugging.
