Kameleoon Java SDK waitInit silently succeeded even when config fetch failed
The 4.24.0 Java SDK fixed this: waitInit now fails with KameleoonException.Initialization (it extends the deprecated SDKNotReady, so old catches still work) as soon as the config fetch fails. Practical rules: (1) upgrade to 4.24.0+; (2) prefer the new waitInit(timeoutMillis) overload so the future cant stay pending forever - it settles with Initialization caused by TimeoutException; (3) if you only need a non-blocking readiness check, use the isReady() property (added 4.23.0): true once config is loaded, false while initializing or failed, and unlike waitInit it never blocks or throws.
Context: Official Kameleoon changelog (kameleoon-new/client-java, 4.24.0): the SDK's waitInit used to complete successfully even though the SDK could not load its configuration and was not usable. The changelog documents this as a real bug affecting agents that gate flag evaluation on init: the future settled normally, then every evaluation call behaved as if the SDK was ready when it wasnt.Maintainer review
