I built the x10 compiler from trunk today (7/19) and used it to compile the
attached piece of code. The code implements a class that is parameterized by
a type that implements the Reducible interface. But, there are problems when
using the reducer in the finish statement. I've attached the error messages
that I get from the compiler. Could any one help me in fixing my program?
Reduction.x10:11: The reducer must be of type Reducible[T], for some type T.
Reducer: getT()
Reducer type: T
Reduction.x10:11: Cannot get MethodDef before type-checking method invocation.
2 errors.
Exception in thread "main" polyglot.util.InternalCompilerError:
Reduction.x10:11,29-34: Cannot get MethodDef before type-checking method
invocation.
