Hi [~lmnet], are you still working on this one? It's been quiet, so if you've
moved on I'd be happy to pick it up. I have a small fix ready (guarding the
numeric inference in {{Values.parseString}} so a top-level value like {{1::2}}
isn't misread as a number, similar to the existing
{{{}true{}}}/{{{}false{}}}/{{{}null{}}} handling). Happy to hand it over or
collaborate, whichever you prefer.

> Key: KAFKA-20892
> URL: https://issues.apache.org/jira/browse/KAFKA-20892
> Project: Kafka
> Issue Type: Bug
> Components: connect
> Affects Versions: 4.3.1
> Reporter: Yuriy Badalyantc
> Assignee: Yuriy Badalyantc
> Priority: Minor
>
> When `SimpleHeaderConverter` tries to decode a header with value like this:
> `1::2`, it mistakenly infers the type of the value as number and returns `1`
> as a result of decoding.
> The reason is in the `Values.parseString` implementation. There was a
> [ticket|https://issues.apache.org/jira/browse/KAFKA-9083] to fix a number of
> similar parsing problems, but this particular problem was not included.
