-----------------------------------
Summary: NPE when jaxb fallback converter is used with
RequestEntityConverter
Key: CAMEL-5890
URL: https://issues.apache.org/jira/browse/CAMEL-5890
Project: Camel
Issue Type: Bug
Affects Versions: 2.10.3, 2.10.2, 2.9.5, 2.9.4
Reporter: Willem Jiang
Assignee: Willem Jiang
Fix For: 2.9.6, 2.10.4, 2.11.0
As the RequestEntityConverter.toRequestEntity(String str, Exchange exchange)
doesn't has check if the exchange is null, it caused the NPE as the user
complain in camel user mailing list[1]
[1]http://camel.465427.n5.nabble.com/Content-Enrich-Error-when-upgrading-Apache-Camel-from-2-9-2-to-any-higher-version-td5724244.html
