> The following code throws a NPE:
>     PropertyValue property = context.getProperty(SOME_PROPERTY);
>     if (property.isExpressionLanguagePresent()) {
> when the property is not set (NULL).
> So I have to write
>     PropertyValue property = context.getProperty(SOME_PROPERTY);
>     if (property.isSet() && property.isExpressionLanguagePresent()) {    
> It would be great if the method isExpressionLanguagePresent() checks for NULL and then return false.
