You are right I need to give more detail.
If the first argument is a String then it is presumed to be a format
specification.
In that case the second argument, if it is a StringBuilderFormattable, has
its formatTo() method called.
[All good]
If the first argument is a Message then the formatTo() is not called.
class Foo implements StringBuilderFormattable {
@Override
public void formatTo(StringBuilder buffer) { buffer.append("bar"); }
}
...
final Message em = log.traceEntry();
...
log.traceExit("{}", new Foo()); // logs the formatTo method [all good]
log.traceExit(em, new Foo()); // logs the toString method *[not what I
expected]*
