#1 Incorrect OJC translation warning (?)

[Michiaki Tatsubori]

Folks,

I have another little bug with OJC. When translating a call to
Math.sqrt, if the argument is a float, it complains. I don't
think it should; the widening-cast from float to double should
be automatic, no? The original code certainly compiled and ran OK.

It produces a warning, but appears to complete the translation OK.
So I guess the warnings are only a nuisance and I can ignore them
safely. But it floods my output a little bit (:-(

Jim

Here is a little test example and the output of running OJC on it,
slightly hand-edited to eliminate irrelevant stuff:

************ Here is the source code that produces the problem

package com.affinnova.EA.Core;

public class Diddle instantiates openjava.mop.OJClass {

public double fiddle(float f) {
return Math.sqrt(f);
}
}

********** Here is the run of OJC translating the above:

C:\dev\coverage>java openjava.ojc.Main Diddle.oj
