I don't remember exactly when lang.reflect.Method.invoke is called.
One place is when you try to call a Java methid (perhaps with the
invoke procedure) but the compiler can't resolve it to a specific
method (or virtual method).
You need to figure out where in the generated bytecode Method.invoke
is called. You can use javap or some other bytecode de-compiiler
or dis-assembler. Once you narrow down wheer the call is coming
from you can add type specifiers to help the compiler.
