Karaf - Kafka OSGI bundle - Producer issue

Question

I am trying to create a simple bundle for Kafka producer in apache Karaf version 4.0.3 .

Here is my Java code

Answer 1

I saw this same problem in 0.9.0. It turned out that a Thread context loader was set, and in that case Kafka uses that classloader to resolve. So the thread context classloader should either be:

• A classloader that can resolve all the Kafka related stuff
• null

Don't know if this is going to bite me, but adding:

Thread.currentThread().setContextClassLoader(null);

did the trick.
