The following code will throw an IllegalArgumentException:

    Class<?> c = Object.class;
    while (true) {
        c = c.arrayType();
    }

With the following stack trace:

    Exception java.lang.IllegalArgumentException
        at Array.newArray (Native Method)
        at Array.newInstance (Array.java:78)
        at Class.arrayType (Class.java:4358)
        at (#2:1)

Class.arrayType does not specify to throw an IllegalArgumentException.
It's specification should be changed to allow it to throw an IllegalStateException, similar to ClassDesc.arrayType().
