Affects PMD Version: 6.22.0
Rule: AbstractClassWithoutAbstractMethod
Description:
When a abstract class contains a abstract inner class which has some abstract methods, then the outer abstract class is not detected, that it has no abstract methods.
Code Sample demonstrating the issue:
Test cases "Abstract class with inner classes false-negative 2" and "Abstract class with inner classes false-negative 3" are failing right now.
