commit 28be7cd6819f0b68380cb22b6ef5c61bdbd019f7
Author: Nicholas DiPiazza <ndipia...@apache.org>
AuthorDate: Sun Dec 28 15:28:02 2025 -0600

    Disable peer class loading to fix classloader conflicts
    
    - Set setPeerClassLoadingEnabled(false) on both server and client
    - Fixes ClassCastException due to class loaded by different classloaders
    - Server uses plugin classloader, client uses app classloader
    - Peer class loading causes the same class to be in both, creating conflicts
    - We don't need peer class loading for our use case
