Summary: Adobe XMP - NullPointerException:

null"org.apache.xmlgraphics.xmp.XMPHandler.getCurrentProperties()" is null
Key: XGC-138
URL: https://issues.apache.org/jira/browse/XGC-138
Project: XMLGraphicsCommons
Issue Type: Bug
Components: xmp
Affects Versions: 2.9
Reporter: Gunnar Hillert
When calling
{code:java}
XMPParser.parseXMP(new StreamSource(new StringReader(xmpString))){code}
with XMP XML that contains facial recognition data, a *NullPointerException* is
thrown:
{code:java}
Caused by: javax.xml.transform.TransformerException:

In order to reproduce, take 1 image with with at least 1 person in it and
import it into {*}Adobe Light Room Classic{*}. Export the original image with
all Metadata intact.
Calling:
{code:java}
XMPParser.parseXMP(new StreamSource(new StringReader(xmpString))){code}
will fail. Taking an image without any humans will work.
As far as I can tell the following additional XML is present in the image with
the human face:
{code:java}
<mwg-rs:Regions rdf:parseType="Resource">
<mwg-rs:AppliedToDimensions stDim:h="3456" stDim:unit="pixel"
stDim:w="4608"/>
<mwg-rs:RegionList>
<rdf:Bag>
<rdf:li>
<rdf:Description mwg-rs:Rotation="0.00000" mwg-rs:Type="Face">
<mwg-rs:Area stArea:h="0.27734" stArea:w="0.20801"
stArea:x="0.57178" stArea:y="0.34180"/>
</rdf:Description>
</rdf:li>
</rdf:Bag>
</mwg-rs:RegionList>
</mwg-rs:Regions> {code}
Once you remove:
{code:java}
<rdf:Description mwg-rs:Rotation="0.00000" mwg-rs:Type="Face">
<mwg-rs:Area stArea:h="0.27734" stArea:w="0.20801" stArea:x="0.57178"
stArea:y="0.34180"/>
</rdf:Description> {code}
the parsing of the XMP XML data will succeed.
