Shutdown failed

Error message

Shutdown failed

What it means

During stop(), invoking the 'shutdown' operation on the lifecycle MBean threw a ReflectionException, meaning the operation exists but its reflective invocation on the MBean failed. The cause is unwrapped (ex.getCause()) and surfaced as MojoExecutionException.

Solutions

1. Inspect ex.getCause() for the real exception behind the reflection failure
2. Review the application's shutdown logs for context-close errors
3. If graceful stop is impossible, terminate the JVM directly and stop the goal

try { client.stop(); } catch (MojoExecutionException ex) { Throwable root = ex.getCause(); log.error("Shutdown reflected failure: {}", root); /* fall back to forced kill */ }

When it happens

Trigger: The shutdown operation on the application's lifecycle MBean threw internally while being invoked reflectively.

Common situations: ApplicationContext.close() threw during shutdown; the MBean was unregistered between the existence check and the invoke; classloader issues during reflective call.
