---------------------------------------
Summary: camel-cxf: Prevent storing invalid entry in Converter
cache on error
Key: CAMEL-19399
URL: https://issues.apache.org/jira/browse/CAMEL-19399
Project: Camel
Issue Type: Bug
Components: came-cxf
Affects Versions: 4.0-M3, 3.20.4, 3.18.7
Reporter: Nicolas Filotto
Assignee: Nicolas Filotto
Fix For: 3.18.8, 3.20.6, 3.21.0, 4.0-RC1
If an error occurs while converting a value thanks to the
`CxfPayloadConverter`, the value `null` is returned to let other fallback
converters to try but if there are no such fallback converters, the cache of
converters will keep the information that no converter exists which is not
incorrect.
The behavior described above occurs when the unit test
`CxfPayloadConverterTest#testInvalidByteArrayToCxfPayload` is called before
`CxfPayloadConverterTest#testByteArrayToCxfPayload`, in that case Camel
believes that there is no converter for a byte array so it returns `null`.
