Description

When you want to format logs in JSON (to be sent to an EFK cluster), we can use this log format pattern :

quarkus.log.console.format={"@timestamp": "%d{yyyy-MM-dd'T'HH:mm:ss.SSS}", "level": "%p", "loggerName": "%C", "message": "%s", "stackTrace":"%e" }%n

However, exception stacktraces will be printed with newlines, which prevent the logs to be cleanly viewed as the log collector will collect each line separately.

Implementation ideas

A way to print the stack trace with newlines replaced by \nas text for stacktrace.
That could be done with a new log pattern symbol like %e or with the support of operator like %replacefor logback (see this stackoverflow issue).
