A DESCRIPTION OF THE PROBLEM :
I'm trying to extract an iFrame's ID from a Document object from the WebEngine. Here are the steps:

- Create a WebView and get the WebEngine.
- Load a URL into the WebEngine by calling WebEngine.load(URL)
- Get the Document object by calling WebEngine.getDocument()
- Get all iframe elements from Document object by calling getElementsByTagName("iframe")

- Loop through the returned NodeList and cast each item as HTMLIFrameElement
- Call method getId() on the HTMLIFrameElement will throw UnsatisfiedLinkError

REGRESSION. Last worked in version 8u51

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It will return the ID of the iFrame set in the HTML
ACTUAL -
throws UnsatisfiedLinkError

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Remove the codes that try to get the iFrame ID
