Description

Two equal instances of an @Immutable class should produce the same value when used as a map key. This is not the case, even though their hash codes are equal.
The last assert below fails, though it should succeed.

@Immutable
final class Foo {
    String bar
}

foo1 = new Foo('bar')
foo2 = new Foo('bar')
assert foo1 == foo2
assert foo1.hashCode() == foo2.hashCode()
fooMap = [(foo1) : 1]
assert fooMap[foo1] == 1
assert fooMap[foo2] == 1 // Fails!!!
