Good point Alex, thanks for contributing – perhaps the upgrade changed the default junit or java version for the project. In any case, the actual cause was less important than my little whinge about the autoboxing ambiguity and how it doesn’t (or shouldn’t) really matter which method gets called in this case.

I’d like to know: Why did an upgrade of Eclipse suddenly start producing these errors? An upgrade of junit or Java 1.4 > 1.5 I might understand but I don’t see how this could possibly be an Eclipse issue…?

The all-object Java with invisible autoboxing already exists: It’s called Scala. It fixes a number of Java’s annoyances concerning types.

Thanks Greg, good point re: doubles.

using assertEquals for doubles is deprecated. You should use a delta/tolerance

If you use assertEquals(double, double, 0.0), the autoboxing ambiguity will take go away as a side benefit.

int/Integer might still be an issue of course…
