Claus Ibsen created CAMEL-26193:
-----------------------------------
Summary: camel-lpr - a Map, POJO, number or null body gives a
print job with null data and no error
Key: CAMEL-26193
URL: https://issues.apache.org/jira/browse/CAMEL-26193
Project: Camel
Issue Type: Bug
Components: camel-printer
Reporter: Claus Ibsen
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.
