@dvohra21 you are not helpful in any way here. The code you mention doesn't come from the op. I question where you get it from. There is no need to state the obvious 'Called DataObject.find on null' here
Yes I am trying to add a new swing form in an application and I am getting the same error for all option i.e. for JFrame, JPanel, JDialog,etc
I just built a fresh swing/awt application (no adf) using 12c and it worked OK. No problem at all.

Please describe in detail what you did to get to the error.
First I created a new Java Desktop Application in which a project is created. Then in that project I am trying to add a JFrame and I am getting the said error.

I am getting following message in extensions log tab of jdeveloper 12c:
Warning: No extension dependency from oracle.forms.pjc to oracle.ide.gallery although oracle.forms.pjc consumes hook javax.ide.extension.ElementName[namespaceURI=http://xmlns.oracle.com/jdeveloper/1013/extension, localName=gallery] , defined in oracle.ide.gallery . The hook will be processed, but is not guaranteed to work every time unless a direct dependency exists.
- Warning: contains deprecated element
Is this warning causing error when I am inserting JFrame.
I am also receiving this error. After creating a new Java Desktop Application, when I try to add a new Swing/AWT JFrame Form or Frame Form I receive this error. Has there been any resolution to this issue?
