Today we check for a few cases where we should maybe die before failing the engine (e.g., when a merge fails). However, there are still other cases where a fatal error can be hidden from us (for example, a failed index writer commit). This commit modifies the mechanism for failing the engine to always check for a fatal error before failing the engine.

As long as you're using Optional here, I think this could be
ExceptionsHelper.maybeError(maybeFatal, logger).ifPresent(e -> {
try {
logger.error(maybeMessage, e);
} finally {
throw e;
}});Up to you if you want though

Extremely insignificant, but just for clarity: I think you mean "does" (indeed contain a fatal error) on this line.

Thank you @richardun, I appreciate the attention to detail. I will push a correction in the morning.
