The `StackWalker` API depends on Streams, which is likely to have lambdas in
its implementation. To avoid the possibility of bootstrap problems, I have
changed the code to use `Thread.currentThread().getStackTrace()`, which is used
by `Throwable.printStackTrace()`. Since `printStackTrace()` is supposed to be
useable at very early bootstrap stages, we are sure no lambdas will be used.
Unfortunately `getStackTrace()` doesn't return the `Class` object, so I have to
use the class's name.
