So clearly it has to be some variant of a not-clean-build, so you need
to check your build/deploy/test strategy.
I'ld suggest removing references to any of the cocoon 1-4 jars and do a
clean rebuild of your complete project, chances are you do have some
lingering calls/references in there to the old stuff...
You might want to check your deployment process as well, maybe newer
versions of your jars aren't uploaded to the test-environment, or
they're not overwriting/removing the old ones and name/version-numbers
are putting them behind the old ones in the classpath (so you still have
the old ones loaded)
One way to detect this last issue is by calling
classloader.getResource("be/sofico/MyApple.class") and see from which
jar your class gets loaded...
Maybe also compare checksums on those jar-files ensuring it's in sync
with the version you've just been cleanly-rebuilding..
