There are several differences in elytron/src/test/resources/logging.properties against other test logging configurations that need some unification (the tests produce unnecessary TRACE log messages by default)

• logger.level
• handler.CONSOLE.target
• handler.CONSOLE.level

For example, compare

• https://github.com/wildfly/wildfly-core/blob/b90ea4eedbb110475e2cfa67cedb617806b1bb3f/elytron/src/test/resources/logging.properties
• https://github.com/wildfly/wildfly-core/blob/b90ea4eedbb110475e2cfa67cedb617806b1bb3f/jmx/src/test/resources/logging.properties

This was revealed thanks to JBEAP-25319, as this is another/next part of the same problem. Current workaround is to adjust/turn off the logging in test executions.
