Description
FULL PRODUCT VERSION :
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) Server VM (build 25.60-b23, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux ubuntu 3.19.0-26-generic #28-Ubuntu SMP Tue Aug 11 14:16:45 UTC 2015 i686 i686 i686 GNU/Linux

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

+1 Tested on Mac and Linux. Both the original IFrame.java test program and the newly added unit test fail without the fix and pass with the fix.

I can test the patch on OS X and Linux and add my comment. Alexander Z will need to push this after he reviews it.

Please find attached fix and regression test. Please review. I will need some help to push it.

@Ilya: can you attach the partial patch you were working on for this bug?

This is not surprising, since 8u60-b09 was when the new WebKit was integrated.

Lowering to P3 given that the impact is limited to two methods in the DOM API.

This issue is regression introduced by changes in revisions 8755 and 9030. As part of integrating the new webkit in revision 8755 _Java_com_sun_webkit_dom_HTMLElementImpl_getIdImpl was removed from modules\web\src\main\native\Source\WebCore\mapfile-macosx along with other changes (see below) As part of 9030 get id and set id were moved from HTMLElementImpl to base class ElementImpl. Neither of these revisions exported _Java_com_sun_webkit_dom_ElementImpl_getIdImpl and _Java_com_sun_webkit_dom_ElementImpl_setIdImpl (see mapfile-macosx and mapfile-vers) and hence attached IFrame.java compiles but does not link at runtime. > hg diff -r 8754 -r 8755 modules\web\src\main\native\Source\WebCore\mapfile-macosx > 8755 - RT-36726: Update to the Latest Version of WebKit + ... - _Java_com_sun_webkit_dom_DocumentImpl_getItemsImpl - _Java_com_sun_webkit_dom_HTMLElementImpl_getIdImpl - _Java_com_sun_webkit_dom_HTMLElementImpl_setIdImpl - _Java_com_sun_webkit_dom_HTMLElementImpl_getItemIdImpl - _Java_com_sun_webkit_dom_HTMLElementImpl_setItemIdImpl - _Java_com_sun_webkit_dom_HTMLElementImpl_getItemScopeImpl - _Java_com_sun_webkit_dom_HTMLElementImpl_setItemScopeImpl - _Java_com_sun_webkit_dom_HTMLIFrameElementImpl_getSeamlessImpl - _Java_com_sun_webkit_dom_HTMLIFrameElementImpl_setSeamlessImpl - _Java_com_sun_webkit_dom_ProcessingInstructionImpl_getDataImpl - _Java_com_sun_webkit_dom_ProcessingInstructionImpl_setDataImpl > hg diff -r 9029 -r 9030 modules\web\src\main\java-wrappers\com\sun\webkit\dom\HTMLElementImpl.java > hg diff -r 9029 -r 9030 modules\web\src\main\java-wrappers\com\sun\webkit\dom\ElementImpl.java > 9030 - summary: 8090062: Update java-wrappers for WebKit generated classes following WebKit update While looking at these methods in latest JDK 8 sources I found that: * getIdImpl/setIdImpl: get id and set id were moved to base class but are not exported in mapfile-macosx (hence code compiles but does not link) * setItemIdImpl: WHY Java_com_sun_webkit_dom_HTMLElementImpl_setItemIdImpl is still exported in mapfile-vers but not in mapfile-macosx while there is no such method in java class? I think it just needs to be removed. * setSeamlessImpl: WHY Java_com_sun_webkit_dom_HTMLIFrameElementImpl_setSeamlessImpl is still exported in mapfile-vers but not in mapfile-macosx while there is no such method in java class? I think it just needs to be removed. * getItemsImpl/getItemIdImpl/getItemScopeImpl/setItemScopeImpl/getSeamlessImpl/getDataImpl/setDataImpl: are not present anywhere in source Do you mind if I take over the CR?

Actually, I was running on an 8u60 EA build on Windows when I said I could reproduce it. With the fcs buld (b27) I cannot reproduce it on 8u60. Since this is reported on Linux I will try there in case it is Linux-specific.
04-09-2015
I can reproduce this with JDK 8u60, but not with the latest EA build of JDK 9. I will try with 8u66.
04-09-2015
It looks like this issue was introduced by previous WebKit merge JDK-8098296, 8u60-b09.
27-08-2015
This will need to be backported to 8u-dev
