Hi Gary,
unfortunately I cannot test against a Git master build today.
What I have done for now is to strip my test setting to log4j2 only (no more
slf4j).
I generated a small test project using log4j2 version 2.7 and junit only:
*pom.xml*

null, "test {}", args);

((ExtendedLogger)log4JLogger).logIfEnabled("test", Level.ERROR,

System.out.println("args " + Arrays.toString(args));

Executing the test above yields to the following result, where {{args}} are
still resetted:
