Insert empty field CDATA into an XML file using JDOM

I'm trying to insert a CDATA field in a xml file using JDOM.
The problem is that the empty field is shown in the xml file like
</content>
and not like
<content></content>

It happens when the field value is like="" (then i get </content>)
If field value is "something" the <content>something</content> is correctly shown

The code i'm using is:
Element content = new Element("content");
CDATA cContenuto = new CDATA(value);
content.addContent(cContenuto);
container.addContent(content);

Someone can help me please?
tanx a lot for the answers!!

Since both forms represent valid XML there should be no problem with either <content/> or <content></content> . Any parser/process that is complaining about <content/> is not XML compliant and a bug report should be raised against it.

You have been very kind, tanx for the answer.
I have tryed to validate the xml file and is correct as you said.

It's "thanks", please, not "tanx".

My apologize.
English is not my motherlanguage.

I was at work and i was tiping as soon as i could.
This is why i used the "contract" form of thanks.

I did not want to offend anyone.

Apologies accepted.
