Read Original

The article details a subtle issue in Java's java.lang.Enum where using getClass() on an enum constant behaves differently for enums with abstract methods versus simple enums, causing an IllegalArgumentException. It explains the problem, provides a test case to reproduce it, and offers the correct solution using the getDeclaringClass() method as per the Java documentation.
