In some cases annotations on type variables are not seen in their typeBindings.

In code like:

  static class Ordering<T extends @Nullable Object> { }

  abstract class NullsFirstOrdering<TTT extends @Nullable Object> extends Ordering<@Nullable TTT> {

The @Nullable annotations on type variable TTT in Ordering<@Nullable TTT> are not seen through the type binding, ie.
typeBindingForOrderingTTT.getTypeArguments()[0] has empty getAnnotations() and getTypeAnnotations(), in fact the type binding returned as the same instance as the one in the definition.

This repros in JDT 4.29 and JDT 4.32.

JDT 4.27 is the last where the annotations are correctly returned.
