In short, comparing two array types should delegate to equality of their component types. Instead, javac uses a more complex routine (containsTypeEquivalent) that, in case equality fails, will check whether the types contain each other. Since this test only makes a difference with wildcards, and since wildcards cannot be array component types, this code should be simplified.
