NPE when running the container with 'disableESLogger()' config

[cristibozga]

Hello.
I'm using the following config:

ElasticsearchClusterRunner.Configs configs = ElasticsearchClusterRunner.newConfigs()
               .clusterName("es-test")
               .numOfNode(1)
               .disableESLogger()
               .printOnFailure();

but when I start the runner I get a NPE:

Caused by: java.lang.NullPointerException: Cannot invoke "org.elasticsearch.logging.internal.spi.LoggerFactory.getLogger(java.lang.Class)" because the return value of "org.elasticsearch.logging.internal.spi.LoggerFactory.provider()" is null
	at org.elasticsearch.logging.LogManager.getLogger(LogManager.java:35)
	at org.elasticsearch.plugins.scanners.ExtensibleFileReader.<clinit>(ExtensibleFileReader.java:24)

I see that in the class ElsticsearchClusterRunner al the line 465 we skip the config of the logger, so LoggerFactory.provider() will return null.

I use Elasictsearch 8.7.1 and elasticsearch-cluster-runner 8.7.1.0

Thanks in advance

Do you use log4j 2.19.0?
Elasticsearch depends on it.

yes, I use exactly that version of log4j.
but as I explained in my comment LoggerFactory.provider() will return null as the init of the logger is skipped
