NPE was happening on `?.takeIf { it.get(arguments) != it.get(newInstance) }` line.
It was happening because `it.get` could return `null`.
But the problem was only reproducible on TeamCity and not reproducible locally.
Test example (IJ repo): `org.jetbrains.kotlin.idea.fir.completion.HighLevelJvmBasicCompletionTestGenerated$Common$FromSmart.testArrayLiteralAnnotationConstructorAsDefaultValueForArray`
stacktrace:
```
java.lang.NullPointerException
