ConnectionBase logs NULL messages even with FINE log level about quarkus HOT 6 OPEN

Are you paraphrasing your log, or is that the exact, literal JSON block that you are seeing in the file?

from quarkus.

I have some other data, here is a more complete log (it comes from a pod in openshift, I have not reproduced the problem in local dev mode yet):

{
  "timestamp":"2024-05-31T10:40:19.730259939Z",
  "host":"worker-04.mydomain.com",
  "level":"SEVERE",
  "loggerName":"io.vertx.core.net.impl.ConnectionBase",
  "mdc":{},
  "message":"NULL",
  "podName":"myapp-5957497c59-pkldh",
  "processId":1,
  "processName":"quarkus-run.jar",
  "threadId":27,
  "threadName":"vert.x-eventloop-thread-1"
}

OK, that helps, thanks. Is this with the included io.quarkus:quarkus-logging-json or with the Quarkiverse io.quarkiverse.loggingjson:quarkus-logging-json?

from quarkus.

We developed our own logging extension based on io.quarkus:quarkus-logging-json

from quarkus.

Can you give me some feedback about this issue? Is it a bug on io.quarkus:quarkus-logging-json?
Just to know if we have to investigate on our side.

from quarkus.

Since I am still facing the issue, I keep investigating on my own and here are some additionnal infos:

I deactivated our JSON logging extension based on io.quarkus:quarkus-logging-json and redeployed my app on openshift. The NULL logs are still present (so I think it is not a problem with JSON logging):

2024-06-18 01:22:52,955 ERROR [io.ver.cor.htt.imp.HttpClientRequestImpl] (vert.x-eventloop-thread-0) NULL
2024-06-18 01:22:52,955 ERROR [io.ver.cor.net.imp.ConnectionBase] (vert.x-eventloop-thread-0) NULL

However, if I set the level of the logger to DEBUG, I can now have additionnal info about the error:

2024-06-18 01:22:52,955 ERROR [io.ver.cor.htt.imp.HttpClientRequestImpl] (vert.x-eventloop-thread-0) NULL
2024-06-18 01:22:52,955 ERROR [io.ver.cor.net.imp.ConnectionBase] (vert.x-eventloop-thread-0) NULL: io.netty.channel.StacklessClosedChannelException

at io.netty.channel.AbstractChannel.close(ChannelPromise)(Unknown Source)

Can someone help me on this please? I would like to be sure there is no bug in background.

Thanks a lot
