Major Description
I am having problems with with class visibility between osgi bundles when using camel 2.12 and 2.13-SNAPSHOT. I have created a showcase to reproduce the problem based on camel example projects. I have tested the created solution in camel 2.10 and problem does not exist.
I have created a sample application which is able to reproduce the problem. Please pick it up from my forked repo:
https://github.com/andrzej-majewski/camel/tree/MvelExpression-class-visibility
The problem occurs when
- camel-example-osgi-domain - project containing only domain classes required by different osgi projects ex.( org.apache.camel.example.osgi.domain.MyPojo )
- camel-example-osgi-mvel - example project which has dependency on camel-example-osgi-domain
Now camel-example-osgi-mvel has following camel context.
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/spring" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> <camelContext xmlns="http://camel.apache.org/schema/spring"> <route> <from uri="timer://mytestTrigger?fixedRate=true&period=10000"/> <to uri="myTestFactory"/> </route> <route id="mvelTest"> <from uri="seda://myMvelTest?concurrentConsumers=2"/> <choice> <when> <mvel>request.body instanceof org.apache.camel.example.osgi.MyPojo</mvel> <to uri="log:MvelRouter"/> </when> </choice> </route> </camelContext> <bean id="myTestFactory" class="org.apache.camel.example.osgi.MyTestFactory"> <property name="numberOfMessages" value="2"/> </bean> </beans>
When I deploy both feature to karaf and place a message on seda://myMvelTest queue I get following exception in karaf.
