`Class <? extends BaseTab> .newInstance () `throws java.lang.StackOverflowError with reflections
code:
Reflections reflections = new Reflections("com.erby.tab.tabs");
for(Class<? extends BaseTab> t : reflections.getSubTypesOf(BaseTab.class)) {
try {
BaseTab tab = t.newInstance();
System.out.println(tab.toString());
} catch (Exception ex) {
ex.printStackTrace();
}
}
BaseTab.java:
public abstract class BaseTab extends Tab implements Serializable {
public abstract String getPrefix();
@Override
public abstract String toString();
}
HomeTab.java:
public class HomeTab extends BaseTab {
public HomeTab() {
setText(toString());
}
@Override
public String getPrefix() {
return "home";
}
@Override
public String toString() {
return "Home Tab";
}
}
When calling this, I get:

FYI BaseTab extends javafx tab.
I found out that it iterates over each class and creates hundreds of instances before it gets an error. Quest where is my code going wrong and how can I fix it? Thank.
