> When log() is called from a class using an instance created/stored at ThreadLocal
> its StackWalker.StackFrame names changes to "WrappingClass$ClassFromThreadLocal".
> This causes NPE because walker.walk(LOCATOR) returns null.
> {code:java}
> StackTraceElement element = walker.walk(LOCATOR).toStackTraceElement();
> {code}
> It is suggested to check the result of walk() for null-ness and react in the way different from NPE.
