ArrayList implementation changed?

[József Rieth]

Hello All,

I have some Java classes extending ArrayList like:

class MyGroup extends ArrayList <Integer> { ... }

It has worked fine till now - but after the latest update there are lots of errors as:

This class must implement the abstract method 'java.util.List<E>.of<E>(E, E, E, E, E, E, E, E)'

Maybe I have to refresh some imports or libraries?

Thanks, Joseph
