Description

In LOG4J2-1255, ggregory stated that he doesn't have a use case for traceExit(R, String, Supplier...) : R.

Here is one:

• R.toString() only produces inadequate information (worst case: it defaults to Object.toString()).

To cope with this, I would like to do the following:

return LOG.traceExit(result, () -> SomeExpensiveToStringHelper.toString(result));

For Logger.traceEntry I already do it like this for those types R which have an inadequate toString() method, but for traceExit I cannot.

So please add traceExit(String, R, Supplier...) : R (Note that the first two parameters have changed places since the original discussion, to mirror the existing traceExit(String, R) : R.)
