NPE in Element.setAttribute(...) - possible bug

Hello list,

 

I'm using JDOM for my project, and I think I have found a bug in the
Element.setAttribute(.) method. If Element.setAttribute(String, String,
Namespace) is called with a namespace that is null, a NullPointerException
is thrown. Here is the relevant part of the stacktrace:

 

java.lang.NullPointerException

                at org.jdom.AttributeList.indexOf(AttributeList.java:378)

                at org.jdom.AttributeList.get(AttributeList.java:366)

                at org.jdom.Element.getAttribute(Element.java:983)

                at org.jdom.Element.setAttribute(Element.java:1157)

 

Elements, however, have the behavior that if you pass in a null Namespace to
the constructor, the namespace is set to Namespace.NO_NAMESPACE. I think it
is logical that the behavior should be the same in attributes. If the list
agrees that this is in fact a bug, I would be happy to provide a patch for
this - it seems to be quite trivial to fix.

 

Best regards,

Karianne Berg
