…osal (apache#11825) * [MNG-8572] Fix @PreDestroy ClassNotFoundException caused by premature ClassRealm disposal The Plexus Disposable.dispose() lifecycle runs before Sisu's @PreDestroy callbacks. When dispose() called flush(), it disposed ClassRealms before @PreDestroy methods on beans loaded from those realms could execute, causing ClassNotFoundException. Change dispose() to only clear the cache map without disposing realms. The flush() method (used for explicit cache clearing between builds) remains unchanged. ClassRealms are disposed when the PlexusContainer shuts down after all lifecycle callbacks complete. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Add test for dispose() vs flush() ClassRealm behavior Verifies that dispose() clears the cache without disposing ClassRealms (so @PreDestroy callbacks can still execute), while flush() disposes both the cache and the realms.
