Not a fan of Throw within a Catch.
Maybe you can wrap it in something else.

I think this is fine because we don't want to wrap or modify the original exception, and it is helpful to log the metadata location that was not correctly deleted.

I think we may leverage runSafely that was added recently.
ExceptionUtil.runSafely(
() -> {
if (errorThrown) {
// if anything went wrong, clean up the uncommitted metadata file
io().deleteFile(metadataLocation);
}
return Void.TYPE;
},
e -> LOG.error("Failed to cleanup metadata file at {}", metadataLocation, e),
() -> unlock(lockId));
