We want to log messages using the EcsLayout in a Java app and when we add a KeyValuePair like  
 where branch is a log4j is a field in  
[org](eclipse-javadoc:%E2%98%82=MatafC the Ecs layout builds incorrectly in the log record a field  
branch= instead of labels.BRN=.  
Would appreciate for advise how to overcome this problem. lient/%5C/UserLibraries%5C/ClientLib%5C/log4j-api-2.17.2.jar%3Corg).apache.logging.log4j.ThreadContext
