CLASS_SHOULD_NOT_BE_ABSTRACT breaks code when abstract class implements an interface

[petertrr]

Describe the bug

interface I {
    fun foo()
}

abstract class A : I  // diktat raises CLASS_SHOULD_NOT_BE_ABSTRACT, changes `abstract` to `open` and breaks compilation

class B : A() {
    override fun foo() {}
}

Observed behavior

Diktat raises CLASS_SHOULD_NOT_BE_ABSTRACT, changes abstract to open and breaks compilation

Environment information

• diktat version: 1.0.1
