ApplicationContextException class

The error a context throws when one of its own steps fails, as opposed to an error in creating a bean.

Today it is thrown when a Lifecycle bean fails to start: the message is "Failed to start bean 'x'" and the bean's own error is the cause. Applications receive it from refresh() or start(); they do not throw it.

// Report which bean failed to start, and why.
try {
  context.refresh();
} on ApplicationContextException catch (e) {
  log.error(e.message, error: e.cause);
}

Spring (Java):

} catch (ApplicationContextException ex) { ... }
