You can use "gij" to run a Java bytecode (i.e. .class) file.

You can also call Java's class loader from compiled native code to
load and run interpreted Java code .

You don't link the compiled code with the bytecode.  You just use a
class loader at runtime to read in the class files.

Alternatively, you can directly call compiled code from intepreted
Java: this works by loading the compiled Java from a shared library,
which is a trick the interpreter can do.
