What problem does this code solve?
In the JSON Pointer spec, "#" and "" are equivalent strings

Risks
Low. This adds required functionality to an ancillary JSON-Java feature. While existing apps may erroneously depend on the existing behavior, this is still a relatively new feature.

Changes to the API?
No.

Will this require a new release?
May be rolled into the next release.

Should the documentation be updated?
No.

Does it break the unit tests?
No, but a new unit test is added to exercise this code change.
