I imported a project from my 3.4.1 workspace into a new workspace for
I20090312-2000. JDT doesn't seem to like one of my unit tests anymore.
Here is a similar snippet that compiles in 3.4.1 but not 3.5
@Test
public void ambiguous() {
int i = 1;
assertEquals(i, getBoxed());
}
private Integer getBoxed() {
return Integer.valueOf(1);
}
"The method assertEquals(Object, Object) is ambiguous for the type
AmbiguousTests"
Is there a preference to control this particular error? Perhaps
something I had set in 3.4 that I don't have set in my new workspace..
Thanks
Ben

It's JUnit 4.4 (or later) that introduces a new overload of assertEquals
that make a call like yours ambiguous.
To avoid the problem, make sure that you either call
assertEquals(Object, Object) (by passing two Integers) or
assertEquals(int, int) (by passing two ints).
Eclipse 3.4 embeds JUnit 4.3.1, while the new 3.5 embeds JUnit 4.5 (if I
remember well).
Mauro.
