**Expected behavior**
Request Logs print in console

**Actual behavior**
Request logs are showing but also too many exceptions only if i set quarkus.http.access-log.enabled=true


**To Reproduce**
Steps to reproduce the behavior:
1. build quarkus project with gradle
2. set quarkus.http.access-log.enabled=true in application.properties
3. Send multiple requests to server with jmeter or ab or maybe wrk.

**Configuration**
```properties
# Add your application.properties here, if applicable.
quarkus.application.name=appname
quarkus.application.version=1.0.0
quarkus.container-image.group={GITHUB_USERNAME}/{REPO}
quarkus.container-image.registry=docker.pkg.github.com
quarkus.jib.base-registry-username={GITHUB_USERNAME}
quarkus.jib.base-registry-password={TOKEN}

quarkus.http.port=8282

quarkus.shutdown.timeout=40

quarkus.http.access-log.enabled=false

quarkus.vault.tls.skip-verify=true

quarkus.vertx.max-event-loop-execute-time=4s

quarkus.http.read-timeout=120s
quarkus.vertx.eventbus.connect-timeout=120s

quarkus.resteasy.gzip.enabled=true
quarkus.resteasy.gzip.max-input=10M
```
