Can I customize the language used by JBoss Logging without changing the JVM user.language option?

Issue

Currently our logs are being shown in regional language (e.g. pt_BR). That makes it hard to search it in Google / Customer Portal and also the translations do not always make sense.

We would like to have an option to set JBoss Logging's language, but keep the JVM's language (user.language, user.region, etc) set to regional values. So, ideally we wanted something like:

JAVA_OPTS="-Duser.language=pt_BR -Djboss.logging.language=en_US"
