-------------------------------------
[~lmnet] thanks for offering to take a look! I've raised a PR for this ticket.
Small change guarding the numeric parsing in {{{}Values.parseString{}}},
similar to how it's done in {{{}canParseSingleTokenLiteral{}}}.
> SimpleHeaderConverter infers a string header as a number if it starts with a
> digit

> 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: Pranav Siby
> 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.
