----------------------------------------------------------------
Key: CAMEL-4781
URL: https://issues.apache.org/jira/browse/CAMEL-4781
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Willem Jiang
Assignee: Willem Jiang
Fix For: 2.9.1
The NoTypeConversionAvailableException message is misleading when it is caused
by other exception.
It just eats up the cause message and let us think there is no converter which
can turn an InputStream
into a Dom from theThe below exception stack trace.
