> under unknown conditions, i get a NPE in get property info, such as the 'getValue()' of the getstring dav property is null:
>             } else if (props.contains(JCR_GET_STRING)) {
>                 // single valued non-binary property
>                 String str = props.get(JCR_GET_STRING).getValue().toString();
>                 QValue qValue = ValueFormat.getQValue(str, propertyType, getNamePathResolver(sessionInfo), getQValueFactory(sessionInfo));
>                 return new PropertyInfoImpl(propertyId, p, propertyType, qValue);
>             } else {
> the other properties in the propset are:
>  - getstring: null
>  - type: String
>  - length: 0
> the property in question is the last property of a node and it's an empty string. the error only occurs on certain usage patterns, but consistently. maybe depending on the fetch-depth or internal cache.
> extending the check to:
>             } else if (props.contains(JCR_GET_STRING) && props.get(JCR_GET_STRING).getValue() != null) {
> solves the problem.
