Parsing bug with sealed interfaces / StackOverflowError #272
Description
Hi
we ran into a problem with qdox leading to a StackOverflowError when calling the method isA(String fullyQualifiedName) on an instance of DefaultJavaClass. This was happening because this instance contained a reference to itself in its implementz list.
We looked a bit further as to why this is happening and found out that the parser does something weird in combination with sealed interfaces.
With this code:
public class Outer {
public sealed interface TheInterface permits Subclass1, Subclass2, Subclass3 {
}
public static non-sealed class Subclass1 implements TheInterface {
}
public static non-sealed class Subclass2 implements TheInterface {
}
public static non-sealed class Subclass3 implements TheInterface {
}
}and then creating a JavaProjectBuilder with the source directory of this file added to the source tree, calling getClasses on the resulting JavaProjectBuilder you get 5 objects of type JavaClass:
- Outer
- TheInterface
- Subclass1
- Subclass2
- Subclass3
The list called implementz of Subclass1 has a size of 4, containing references to TheInterface, Subclass1, Subclass2, Subclass3. The other ones seem to be correct, only having TheInterface as parent. It seems to only affect the first class coming after the interface.
