Hello!
I just noticed that the Java thin client throws the following internal
exceptions:
ClientProtocolError
ClientError
Since the classes are not public, there is no way to catch them properly in
user code.
Consider the recent changes, introduced by IGNITE-9410:
throw new ClientProtocolError(String.format("Transactions have not
supported by the server's " +
"protocol version %s, required version %s",
req.clientChannel().serverVersion(), V1_5_0));
The code above correctly verifies the server version against the current
client and throws an exception
In case of an outdated server. The only way to catch it in user code is by
RuntimeException
that feels too broad to use.
I’d like to discuss what’d be the best option to handle this scenario:
- Should we make the ClientError public?
- Should we introduce a new public error for every particular
exception?
- Just ignore this?
Thoughts?
