Reason for java lang IncompatibleClassChangeError

Question

I'm trying to package a Java library as a JAR. But when whenever I am invoking its methods it throws some random java.lang.IncompatibleClassChangeErrors. How do I debug this?

Answer 1

Well these kinda error generally occur when you alter the library codes without recompiling the client code. So, you should try recompiling the client code against the new library. I guess this might solve your issue. For more details, you can refer here: Java Language Specification §13.
