Hi Alexandru,

I'm feeling the same way, glad you brought it up.

Um, yes. I'm in violent agreement ;)

Quite obviously, the java language supports any object variables being set
to null, and the some of the apis also supports setting of null values, for
example: http://java.sun.com/j2se/1.5.0/docs/api/java/util/HashMap.html. The
key is not removed, just the value.

I mean, its fine that there are other ways of doing things, but I'm
surprised that some people don't seem familiar with the Java approach. I'm
NOT surprised that some java developers find it odd that the JCR standard
veers from the Java standard, especially when use cases have been provided
that describe mis-match problems (based on the fact that JCR and Java work
differently wrt nulls). I hope our input can result in some change.
