docs: Given the passed in String class name, return the named JVM class.
  @param name String name of a JVM class.
  @param classLoader ClassLoader to use when searching for JVM classes.
  @param failOnClassLoadingError If named class is not loadable off classpath: true will raise JsonIoException,
  false will return default LinkedHashMap.
  @return Class the named JVM class.
  @throws JsonIoException if named Class is invalid or not loadable via the classLoader and failOnClassLoadingError is
  true
