Description

Using camel-file component(3.18.0) in OSGi environment (Apache Karaf) throws ClassNotFoundException:

Caused by: java.lang.ClassNotFoundException: org.apache.camel.resume.ResumeAware not found by org.apache.camel.camel-file [46]

        at org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation(BundleWiringImpl.java:1591)

        at org.apache.felix.framework.BundleWiringImpl.access$300(BundleWiringImpl.java:79)

        at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.loadClass(BundleWiringImpl.java:1976)

        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520)

The reason may be org.apache.camel.resume package is in Private-Package section of MANIFEST.MF in camel-file bundle (JAR file contains single configuration file: adapter.properties in this package) so exported package of camel-api bundle is hidden. I found that it has been changed since 3.17.x.
