> I am struggling with random deployment failures of bundles containing Camel routes, packaged in a KAR file. Deployment fails mostly because data formats cannot be found on the classpath or Camel component beans are not found in the registry.
> The attached sample KAR file contains one bundle with the following blueprint deployment descriptor:
> {code:xml}
> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" 			xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 			xmlns:camel="http://camel.apache.org/schema/blueprint" 			xsi:schemaLocation="				http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
> 				http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint-2.16.1.xsd">
>  
> 	<bean id="processor" class="ch.rsteppac.karissue.RestProcessor" />
> 	<camelContext id="rest-api" allowUseOriginalMessage="false" xmlns="http://camel.apache.org/schema/blueprint">
> 		<restConfiguration component="netty4-http" scheme="http" host="0.0.0.0" port="2016" bindingMode="json">
> 			<dataFormatProperty key="prettyPrint" value="true" />
> 		</restConfiguration>
> 		<rest path="/say/hello" id="poc-route" produces="application/json">
> 			<get uri="/{yourName}">
> 				<route>
> 					<camel:process ref="processor" />
> 				</route>
> 			</get>
> 		</rest>
> 	</camelContext>
> </blueprint>
> {code}
> The feature file of the KAR:
> {code:xml}
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <features xmlns="http://karaf.apache.org/xmlns/features/v1.3.0" name="KAR deployment issue PoC">
>     <repository>mvn:org.apache.camel.karaf/apache-camel/2.16.1/xml/features</repository>
>     <feature name="poc-rest-service" description="Sample REST bundle to demonstrate the deployment issue in Karaf 4" version="0.0.1.SNAPSHOT">
>         <details>Sample REST bundle to demonstrate the deployment issue in Karaf 4</details>
>         <feature version="2.16.1" prerequisite="false" dependency="false">camel-jackson</feature>
>         <feature version="2.16.1" prerequisite="false" dependency="false">camel-blueprint</feature>
>         <feature version="2.16.1" prerequisite="false" dependency="false">camel-netty4-http</feature>
>         <bundle>mvn:ch.rsteppac.kar-issue/poc-rest-service/0.0.1-SNAPSHOT</bundle>
>     </feature>
> </features>
> {code}
> On my development machine (OSX) deploying the sample KAR file succeeds about 8 out of 10 times. It appears that the more features the KAR file contains the lower the probability of success. Our actual project KAR fails deployment about 9 out of 10 times.
> Not all Camel components are equally likely to cause the deployment failure. The most likely to trigger a failure are data formats, e.g., jackson-json or jaxb.
> Once the KAR file has deployed successfully, restarting Karaf will consistently deploy the bundles successfully. Until one deletes Karaf's data folder, then all bets are off again.
> Adding the feature.xml generated for the KAR with {{feature:repo-add}} and then deploying the features with {{feature:install}} virtually never fails.
> Stack traces for most frequent deployment failure of the sample KAR are attached to the ticket.
