I am using the latest extractor on your website. 2.5.0 RC2

Are you able to provide a sample image?

sure, here is the image attached. This one has xmp meta data in it and throws 
the above exception.

In my case, it was caused by an incompatible xercesImpl.jar.

It was the same with me. The jars were incompatible. I downloaded the latest 
jar file. It works now!

Same problem, using the 2.5.0 RC2.

Build XMPCore from Adobe sources doesn't fix the problem.

Can somebody tell me how to bypass the XMP metadata parsing ?

Observing issue against 2.5.0 RC3

I don't have an update on this right now, though my plan is to restructure the 
API a bit to support external providers, and then make the XMP stuff external, 
and therefore optional.

This would also allow others to provide their own external metadata providers.

---

Note that in this case, the exception is an 'uncatchable' AbstractMethodError, 
indicating:

> Normally, this error is caught by the compiler; this error can only occur at 
run time if the definition of some class has incompatibly changed since the 
currently executing method was last compiled.

http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/AbstractMethodError.html

Therefore the solution to this problem is to have the expected version of all 
jars available.

I'll close this issue and create a 'Troubleshooting' page on the wiki with this 
information.

I had the same problems - for me the following solution worked for this issue:

Apparently the xmpcore.jar delivered with version 2.6.2 calls the method 
javax.xml.parsers.DocumentBuilderFactory.setFeature(java/lang/String). 
Referring to the JDK 5.0 resp. 6.0 Java API Specification the setFeature method 
in DocumentBuilderFactory is however implemented with setFeature(String name, 
boolean value). So I downloaded a current version (5.1.0) of the XMP Library 
for Java CS6 from Adobe and compiled it without any modifications (which 
changes the setFeature() call). Now the following patch has to applied to 
com.drew.metadata.xmp.XmpReader:

@@ -156,9 +156,9 @@
             for (XMPIterator iterator = xmpMeta.iterator(); iterator.hasNext();) {
                 XMPPropertyInfo propInfo = (XMPPropertyInfo) iterator.next();
                 String path = propInfo.getPath();
-                Object value = propInfo.getValue();
+                String value = propInfo.getValue();
                 if (path != null && value != null)
-                    directory.addProperty(path, value.toString());
+                    directory.addProperty(path, value);
             }
