class Parameters uses an instance of the class ParameterReader which is in the very same package, but I get the error message "Cannot find type ParameterReader".

The class Parameters uses an instance of the class ParameterReader which is in the very same package (ssca1). But I get the error message "Cannot find type ParameterReader".
Notice in the finder window ParameterReader.class is the first item in the bin/ssca1 directory. So the question is: do I really have an error, or did the compiler screw up, or the Java translation?
