Their library works without relying on any bug. Some external code relies
on the bug, and just happens to get caught when using their library.
When you feed a null reference to a standard JDK class which reacts
by throwing a NullPointerException, is this a bug of the standard JDK
class, or of the code which calls it incorrectly ?

Same here. EnumUtils expects an initialized class. Some application code
feeds it an uninitialized class. And things break.

What does the docs say?

"class" or "class that must be initialized" ?

First => lib issue

Second => app issue

<http://commons.apache.org/lang/api-release/org/apache/commons/lang/enums/EnumUtils.html>
Every method takes a 'Class' argument about which the method docs all say:

enumClass - the class of the Enum to get

Nowhere do the docs suggest that the class must be initialized first.
