### Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

The class which fails:

```java
public class RelationMemberListMergeModel extends AbstractListMergeModel {
// ...
@Override
protected void buildMergedEntriesTableModel() {
mergedEntriesTableModel = this.new EntriesTableModel(ListRole.MERGED_ENTRIES) { // crash here
@Override
public boolean isCellEditable(int row, int column) {
switch(column) {
case 1: return true;
default: return false;
}
}
};
}
// ...
}
```

Super class with nested class:
```java
public abstract class AbstractListMergeModel extends ChangeNotifier {
// ...
protected EntriesTableModel myEntriesTableModel;
protected EntriesTableModel theirEntriesTableModel;
protected EntriesTableModel mergedEntriesTableModel;
// ...
public class EntriesTableModel extends DefaultTableModel implements OsmPrimitivesTableModel {
private final ListRole role;
public EntriesTableModel(ListRole role) {
this.role = role;
}
// ...
}
// ...
}
```
