> Key: CAMEL-26193
> URL: https://issues.apache.org/jira/browse/CAMEL-26193
> Project: Camel
> Issue Type: Bug
> Components: camel-printer
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0
>
>
> Found while adding the catalog body types of lpr (CAMEL-24961, PR #28414).
> h4. 1. A body that does not convert to InputStream is printed as null data
> {{PrinterProducer.process}} (main 2a465aa4814c, line 55 to 56) converts the
> body with the non-mandatory {{convertTo(InputStream.class, body)}}. For a
> Map, a POJO, a number or a null body the stream is null and the producer
> submits a print job with null data; Camel raises no error. Checked on
> 4.24.0-SNAPSHOT with a mocked PrintService.
> Proposed: use a mandatory conversion so an unsupported body fails the
> exchange.
