John Yin created CAMEL-18279:
--------------------------------
Summary: When run 3.18.0 with Spring Boot, received
java.io.FileNotFoundException: class path resource [.class] cannot be opened
because it does not exist
Key: CAMEL-18279
URL: https://issues.apache.org/jira/browse/CAMEL-18279
Project: Camel
Issue Type: Bug
Components: came-cxf
Affects Versions: 3.18.0
Reporter: John Yin
Attachments: screenshot-camel.png
After upgrading a springboot application to Camel 3.18.0, received the
following exception during startup (Spring AutoConfiguration):
java.io.FileNotFoundException: class path resource [.class] cannot be opened
because it does not exist
It is most likely related to a camel cxf class. A breakpoint in Spring
AutoConfigurationSorter.java shows that the list of camel classNames to be
configured contains an empty class name ("") between
org.apache.camel.component.cxf.jaxrs.springboot.CxfRsComponentConverter and
org.apache.camel.component.cxf.jaxws.springboot.CxfComponentAutoConfiguration.
See the attached screenshots.
