> This blog entry

> shows there is some issue with how parameter annotations work across JDKs.
> Although I think GCJ is actually wrong if you read the javadoc
> http://java.sun.com/j2se/1.5.0/docs/api/java/lang/reflect/Method.html#getParameterAnnotations()
> since the parameter annotations array should be the same length as the number of parameters
> we can certainly give a better error message than an ArrayIndex error.
