Pierre Villard updated NIFI-7845:
---------------------------------
Status: Patch Available (was: Open)
> Insufficient handling on malformed/empty strings
> ------------------------------------------------
>
> Key: NIFI-7845
> URL: https://issues.apache.org/jira/browse/NIFI-7845
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.11.4
> Reporter: Clement
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> At the moment, the `validateAMQPHeaderProperty()` does not handle
> `amqpPropValues` that are appended and prepended by curly braces, like
> `{a=b}`.
> Nor does the function deal with an empty `amqpPropValues` properly.
> This is particularly a problem because if the AMQP queue you're reading from
> with the `ConsumeAMQP.java` processor has a message with an *empty* header,
> then `ConsumeAMQP.java` creates a flowfile-attribute `ampq$header` of the
> form `{}` - which causes `validateAMQPHeaderProperty()` to pollute the NiFi
> error box.
> According to [1] the AMQP header attribute is optional anyway, so we need to
> handle blank entries.
