Use Class.getName() as fallback in HandlerFunctionDescription 

In JDK 15 the concept of hidden classes was introduced, which also
affects Lambdas in so far that Class.getCanonicalName() will return null
for those. This commit uses Class.getName() as a fallback when no
canonical name is available.

See gh-21713
