Summary

0006477: Hessian 4.0.66 Serialize Object with Calendar would fail on deserialization if references are used

Description

If you try to serialize and de-serialize an object with a Calendar instance the de-serialization will fail if references are used. This is because the `Calendar` instance will be replaced with `CalendarHandle`. During de-serialization the index of referenced objects is wrong (real index + 1 for example) because during `Hessian2Output#replaceRef` the `_refCount` will be be unchanged although the refs size will be decreased.

<code>
private static class TestUser implements java.io.Serializable {
        private final String name;
        private final Calendar lastSeen;
    }
</code>
