What happened?

As described in #camel-k > New plain-quarkus option not compatible with --compression whenever you try to apply compression option to an integration with plain-quarkus provider, it fails when trying to start as it treat the compress content as the route source without decompressing it previously.
This situation doesn't appear in default provider "quarkus".

Steps to reproduce

1. Create a basic simple route in Java
2. Execute command: kamel run Basic.java --compression -t camel.runtime-provider=plain-quarkus -t camel.runtime-version=3.28.4
3. Execute command: kamel log basic and you'll get something like:
