## Summary Fixes [CAMEL-25191](https://issues.apache.org/jira/browse/CAMEL-25191) — flaky test `MainNotAutoConfiguredWarningTest`. ## Root Cause `MainNotAutoConfiguredWarningTest` installs a custom WARN appender on the `BaseMainSupport` Log4j logger in `@BeforeEach`/`@AfterEach`, mutating global `LoggerContext` state. Under JUnit parallel execution, `AiObservabilityConfigurationPropertiesTest` concurrently emits WARN logs for unconsumed `camel.aiObservability.enable` properties (loaded from `ai-observability-unknown.properties`). These logs leak into the test appender and cause assertion failures (17% rate normally, 78% with `-T1C`). ## Fix Add `@Isolated` to prevent concurrent test execution while the `LoggerContext` is modified. This is consistent with the existing pattern used by `MainPropertyPlaceholderTest`, `MainEnvVarComponentConfigTest`, `MainPropertyPlaceholderWithEnvTest`, `MainPropertyPlaceholderWithSystemTest`, and `MainBootstrapEdgeCasesTest` in the same module. Also drop `public` modifiers from class and method declarations per JUnit 5 / AGENTS.md conventions. ## Testing `mvn test -pl core/camel-main -am -Dtest=MainNotAutoConfiguredWarningTest` — 2/2 tests pass. -- This is an automated message from the Apache Git Service.
