[jdk20] RFR: 8301863: ObjectInputFilter example incorrectly calls rejectUndecidedClass [v2]

[Roger Riggs]

> The example code in ObjectInputFilter for the FilterInThread filter factory does not do what is intended and is poorly described. Clarifies that the JVM-wide filter and the thread local filter are merged and will reject classes that are otherwise not accepted or rejected. If a stream specific filter is set and does not accept or reject a class, the combined filter is applied.

> This is a doc-only change.
