Hi Ian, the fix is new to me... and also a bit strange, you're basically casting to the superclass of ByteBuffer, where the clear method is defined... but it should be visible by inheritance. See the javadocs: * https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/ByteBuffer.html * https://docs.oracle.com/javase/8/docs/api/java/nio/ByteBuffer.html
The only difference I'm seeing, it's that in java 8 the inherited method is final, but in java 11 it's not... oh that might explain the difference, if the resolution of which method to call it's done at compile time. I guess the code change is not going to break the code, even accessing them method in the context of the base class, inheritance should kick in at run time and have the subclass method be called, right?
