Re: [jboss-dev] inner classes and param types
One way of solving this ...
Type parameterType;
if (parameterTypes.length == genericParameterTypes.length) {
parameterType = genericParameterTypes[i];
} else {
if (gi >= 0)
parameterType = genericParameterTypes[gi];
else
parameterType = parameterTypes[i];
}
... but I would still like to know where does the diff comes from.

Anyone seen this, or how to make this deterministic ...
I have these 2 classes - (a) and (b) - see below.
And this code:
final Annotation[][] parameterAnnotations =
constructor.getParameterAnnotations();
final Type[] genericParameterTypes = constructor.getGenericParameterTypes();
// If the class is a (non-static) member class, its constructors
// parameterTypes array will prefix the
// outer class instance, whilst the genericParameterTypes array isn't
// prefix'd -- not always true ...
int nesting = Reflections.getNesting(declaringClass.getJavaClass());
for (int i = 0; i < parameterTypes.length; i++) {
int gi = i - nesting;
Annotation[] annotations = (gi >= 0 &&
parameterAnnotations[gi].length > 0) ? parameterAnnotations[gi] : EMPTY;
Class<?> clazz = parameterTypes[i];
Type parameterType = genericParameterTypes[i];
So, the issue is - as I added "not always true" to the existing comment,
that "genericParameterTypes" are random in my case --
sometimes they have owner class prefixed == use case (a),
sometimes they don't == use case (b), hence resulting in ArrayIOOBE.
Any idea why is this so?
