GitHub user ppkarwasz added a comment to the discussion: Is using %uuid{RANDOM} pattern in JsonTemplateLayout considered garbage-free?
Neither one is GC-free. Each one will create an instance of [`UUID`](https://docs.oracle.com/javase/8/docs/api/java/util/UUID.html) and `String`. Scalar replacement might occur, when the JVM is hot enough, but you should test it on a concrete version of the JVM.
