2.x Time bounded replaySubject getValue() unexpected behavior

[nathankooij]

Affects 2.1.1.

The Javadoc for ReplaySubject::getValue states the following:

Returns a single value the Subject currently has or null if no such value exists.

In combination with a time bounded replay subject I would expect null if either:

• there has not yet been an emission
• the emitted item's age is too old

Currently this is not the case as demonstrated by the following test: nathankooij@6afa40c
However, getValues() does return null (that is, old items are evicted), which is also demonstrated by the aforementioned test. To me it seems that either the implementation of getValue/getValues is inconsistent with each other, and the current behavior is not obvious to me from the documentation.

I've added what I think could be the fix in: nathankooij@bf1c189

Yes, it looks like an inconsistency. Do you want to post a PR? Please don't forget to verify/fix ReplayProcessor if possible.

[nathankooij]

Yes, will open a PR.
