> If a CoprocessorProtocol derived interface defines a method with a void return type,
the method cannot be called using HTable.coprocessorExec().  Instead ExecResult will throw
an IOException on the client trying to do a Class.forName() on "void".
> Looking at ExecResult, it appears that the valueType field (which causes the error) is
no longer even used, so I'd suggest we just get rid of it.
