You can get annotations on the getter method:

propertyDescriptor.getReadMethod().getDeclaredAnnotations();

Getting the annotations of a private field seems like a bad idea... what if the property isn't even backed by a field, or is backed by a field with a different name? Even ignoring those cases, you're breaking abstraction by looking at private stuff.
