The asCollector transform does not respect the type argument.
When it collects a series of arguments, it always puts it into an Object[] array.
This causes a CCE if the ultimate target requires a more specific type, such as String[].

Here is a customer report:

Also, this reproduces the bug:

MethodHandle asList = lookup().
    findStatic(Arrays.class, "asList", methodType(List.class, Object[].class));

asList = asList.asType(methodType(List.class, String[].class)).
    asVarargsCollector(String[].class);

System.out.println(asList.invokeWithArguments("a", "b", "c"));
