Why does you not throw ArangoDBException in HttpCommunication.java, the inserting action was failed but I cannot handle this event

[truongmaicongtri]

catch (final IOException e) {
hostHandler.fail(e);
if (hostHandle != null && hostHandle.getHost() != null) {
hostHandle.setHost(null);
}
final Host failedHost = host;
host = hostHandler.get(hostHandle, accessType);
if (host != null) {
LOGGER.warn(String.format("Could not connect to %s", failedHost.getDescription()), e);
LOGGER.warn(String.format("Could not connect to %s. Try connecting to %s",
failedHost.getDescription(), host.getDescription()));
<why does you not throw ArangoDBException? at here>
} else {
LOGGER.error(e.getMessage(), e);
throw new ArangoDBException(e);
}
}

The exception is not thrown there because there is another host to try. The exception will be thrown when the host returned from the host handler is null:

arangodb-java-driver/src/main/java/com/arangodb/internal/http/HttpCommunication.java

Lines 83 to 113 in 4626f10

	while (true) {
	try {
	final HttpConnection connection = (HttpConnection) host.connection();
	final Response response = connection.execute(request);
	hostHandler.success();
	hostHandler.confirm();
	return response;
	} catch (final SocketTimeoutException e) {
	// SocketTimeoutException exceptions are wrapped and rethrown.
	// Differently from other IOException exceptions they must not be retried,
	// since the requests could not be idempotent.
	TimeoutException te = new TimeoutException(e.getMessage());
	te.initCause(e);
	throw new ArangoDBException(te);
	} catch (final IOException e) {
	hostHandler.fail(e);
	if (hostHandle != null && hostHandle.getHost() != null) {
	hostHandle.setHost(null);
	}
	final Host failedHost = host;
	host = hostHandler.get(hostHandle, accessType);
	if (host != null) {
	LOGGER.warn(String.format("Could not connect to %s", failedHost.getDescription()), e);
	LOGGER.warn(String.format("Could not connect to %s. Try connecting to %s",
	failedHost.getDescription(), host.getDescription()));
	} else {
	LOGGER.error(e.getMessage(), e);
	throw new ArangoDBException(e);
	}
	}
	}
