| Doc Text: |
Previously the `hello.properties` file was located in `org/apache/qpid/example` (together with the example sources) and the binaries were compiled to the same location. Starting with MRG-3.1, the source and hello.properties location was changed to src/main/java/org/apache/qpid/example/ while the compiled binaries were still saved to the old location. This caused the Hello example to not be able to read the `hello.properties` file and resulted in a NullPointerException.
The bug fix permanently moves the java source for examples into `/examples/org` instead of `examples/src/main/java/org` which puts the content back into the correct classpath context for the example start script. This corrects the workaround present in https://bugzilla.redhat.com/show_bug.cgi?id=1206503[BZ#1206503].

The hello.properties is loaded via the classpath. Therefore it needs to be within a jar file (where Hello.java code is packaged) or in a path where Hello.java is compiled to when run_example.sh is executed. This is best handled by whoever is creating the rpms as run_example.sh is a rpm specific artifact and not present in upstream. I haven't been creating rpms for a while and therefore, 1. It would be faster for the maintainer to handle this, as I will have to re-orient myself with the new setup. 2. I don't know the reason why the structure was changed. Therefore this change is best handled with the person who changed the paths to figure out why it was done. If assistance is required, I'm happy to help. Hi Irina. I've created a release note for this because it corrects a Known Issue from the previous z-stream. Let me know if the wording is OK, bearing in mind the material change was to move files around, and that particular comment was set to private.
