I noticed this because it crashes ASM [1], not because of an issue with
reflection. But accessing it reflectively as you describe does blow up:

((ParameterizedType)
Test.class.getField("i").getGenericType()).getActualTypeArguments()
...
GenericSignatureFormatError: Signature Parse error: Expected Field Type
Signature
Remaining input: *>.I;
at
sun.reflect.generics.parser.SignatureParser.error(SignatureParser.java:124)
at
sun.reflect.generics.parser.SignatureParser.parseFieldTypeSignature(SignatureParser.java:297)

If you're interested in pursuing the first option Maurizio described, I'd
be happy to help assess the compatibility impact on our code.
