This happens when I try to create a hierarchy search scope for java.util.ArrayList and google.guava is on the class path of the current project. The code that throws the NPE is if (methodDescriptor != null) { MethodBinding enclosingMethod = findMethod(methodDescriptor, missingTypeNames); typeVars = enclosingMethod.typeVariables; } where the enclosingMethod is null. Any idea for a workaround is highly appreciated. The problematic type seems to be com.google.common.collect.StandardTable$Row$RowEntrySet$1 which is a private inner class in a private inner class: private class RowEntrySet extends Maps.EntrySet<C, V> { @Override Map<C, V> map() { return Row.this; } @Override public int size() { Map<C, V> map = backingRowMap(); return (map == null) ? 0 : map.size(); } @Override public Iterator<Entry<C, V>> iterator() { final Map<C, V> map = backingRowMap(); if (map == null) { return Iterators.emptyModifiableIterator(); } final Iterator<Entry<C, V>> iterator = map.entrySet().iterator(); return new Iterator<Entry<C, V>>() { @Override public boolean hasNext() { return iterator.hasNext(); } @Override public Entry<C, V> next() { final Entry<C, V> entry = iterator.next(); return new ForwardingMapEntry<C, V>() { @Override protected Entry<C, V> delegate() { return entry; } @Override public V setValue(V value) { return super.setValue(checkNotNull(value)); } @Override public boolean equals(Object object) { // TODO(user): identify why this affects GWT tests return standardEquals(object); } }; } @Override public void remove() { iterator.remove(); maintainEmptyInvariant(); } }; } }

3.5.2? wow :) Have you tried this using a more recent version?
(In reply to comment #1) > 3.5.2? wow :) > Have you tried this using a more recent version? Hmm seems to work fine with 3.8.x Any hint on where to put a reasonable try { } catch for 3.5.2?
