> When using the NTCollectionConverterImpl with proxy=3D"true" a call on th=
e size () method of a ManageableArrayList causes a NullPointerException if =
there is no underlying List. LazyCollectionLoader doLoad returns null becau=
se there is are no children.
> The ManageableArrayList is created because the isNull method of the NTCol=
lectionConverterImpl class always returns false.=20
> According to the comment line this is done because the getCollectionNodes=
 always returns a list.=20
> But after the fix for JCR-882 this is not correct anymore.
> The attached fix corrects this.=20
> The only question remaining is how to differ between an empty list and a =
null-value for the field containing the list.
