Camel 2 -> 3 migration. OnException & OSGI Classloading
Hi, I'm currently migrating an OSGI application from Camel 2.25 to 3.21. I've encountered a change in the way onException deals with the type it's asked to handle in an OSGI environment. In 2.25 the OnExceptionDefinition instance keeps a reference to the classes it's asked to handle (in the exceptionClasses field). In 3.x it just stores the names of the exception classes it should handle. When the ProcessorReifier builds the route it then loads the required classes named on the definition. My issue is that my camel context is created in one OSGi bundle (with one classloader) and the route added from a different bundle (with its own classloader). In 2.x this worked fine. In 3.x the route can't be started (as the context's classloader can't see the exception class). This design is used to permit plugin modules to add their own routes to the core application's context. Has anyone experienced the same issue and found a solution? I don't want to add Import-Package instructions to the bundle with the Camel Context - as this would break the plugin module design. Using DynamicImport-Package: * in my camel context bundle does resolve the issue but doesn't seem ideal - my plugin bundle should be resolving the exception class. Thanks, Paul

Subject: [Camel Mail Component] Caching MimeMultipart
Hi everyone,
We are using the Camel Mail component to fetch mails from a mailbox. The camel
exchange will provide the MimeMultipart Object in the exchange body.
We now see that every access to this MimeMulitpart will do a remote call to the
mailserver. Is there any setting in camel that allows us to prevent this, i.e.
by caching the data once it has been loaded?
Best regards,
Manuel
Example
Processor:
Each time getBody(String.class) is called, a remote calls to the mailserver are
done.
public void process(Exchange exchange) throws Exception {
System.out.println("TEST 1.\n" +
exchange.getMessage().getBody(String.class));
System.out.println("TEST 2.\n" +
exchange.getMessage().getBody(String.class));
System.out.println("TEST 3.\n" +
exchange.getMessage().getBody(String.class));
}
After running above lines with debugMode=true, I can see the remote calls:
A13 FETCH 1 (BODY.PEEK[1.1])
* 1 FETCH (BODY[1.1] {30}
