> Key: CAMEL-11609
> URL: https://issues.apache.org/jira/browse/CAMEL-11609
> Project: Camel
> Issue Type: Bug
> Components: camel-csv
> Affects Versions: 2.19.1
> Reporter: Daniel Baldes
> Assignee: Andrea Cosentino
> Fix For: 2.20.0

>
> org.apache.camel.dataformat.univocity.Marshaller.java is not thread safe.
> When this.adaptheaders is true, this.headers is modified in the wirteRow() method. This can lead to ConcurrentModificationExceptions (see below) and jumbled headers, occasionally.
> I use a {{UnivocityCsvDataFormat}} for marshalling CSV in a route which is called in parallel. The DataFormat creates a Marshaller with adaptheaders == true when headers are not specified in the format.
