It seems like the quoted documentation is for 'getStackTrace()' method. :)

Anyway, you're right. But what about parsing stack trace strings to find out
the class name? This should work for most virtual machines. In case of
failure we could throw a RuntimeException to trigger
ExceptionInitializerError.
