NoSuchElementException when solving type

[4everTheOne]

There's a bug in the class JavaParserClassDeclaration that doesn't allow the resolution of the following example code.
This example was taken from Guava Collect Spliterators as a sample:

package com.example;

import java.util.Comparator;
import java.util.Spliterator;
import java.util.function.Consumer;
import java.util.function.IntConsumer;
import java.util.function.IntFunction;
import java.util.stream.IntStream;

public class TestClass {

    static <T> Spliterator<T> indexed(int size, int extraCharacteristics, IntFunction<T> function, Comparator<? super T> comparator) {
        class WithCharacteristics implements Spliterator<T> {

            private final Spliterator.OfInt delegate;

            WithCharacteristics(Spliterator.OfInt delegate) {
                this.delegate = delegate;
            }

            @Override
            public boolean tryAdvance(Consumer<? super T> action) {
                return delegate.tryAdvance((IntConsumer) i -> action.accept(function.apply(i)));
            }

            @Override
            public void forEachRemaining(Consumer<? super T> action) {
                delegate.forEachRemaining((IntConsumer) i -> action.accept(function.apply(i)));
            }

            @Override
            public Spliterator<T> trySplit() {
                Spliterator.OfInt split = delegate.trySplit();
                return (split == null) ? null : new WithCharacteristics(split);
            }

            @Override
            public long estimateSize() {
                return delegate.estimateSize();
            }

            @Override
            public int characteristics() {
                return Spliterator.ORDERED | Spliterator.SIZED | Spliterator.SUBSIZED | extraCharacteristics;
            }

            @Override
            public Comparator<? super T> getComparator() {
                if (hasCharacteristics(Spliterator.SORTED)) {
                    return comparator;
                } else {
                    throw new IllegalStateException();
                }
            }
        }
        return new WithCharacteristics(IntStream.range(0, size).spliterator());
    }
}

Expected Behavior

When executing the test with the example above the field type should be resolved as java.util.Spliterator.OfInt.

Current Behavior

When resolving the example above an java.util.NoSuchElementException is thrown.
