Ivo Ladage - van Doorn commented on AMDATUOPENSOCIAL-193:
---------------------------------------------------------
The error above can easily be fixed by disabling ehCache (as default for the
normal runtime). But after fixing that error, you get this one instead:
Caused by: java.lang.ClassCastException:
org.apache.xerces.dom.DOMXSImplementationSourceImpl cannot be cast to org.w3c.d
om.DOMImplementationSource
at org.w3c.dom.bootstrap.DOMImplementationRegistry.newInstance(Unknown
Source)

org.apache.shindig.gadgets.parse.ParseModule$DOMImplementationProvider.<init>(ParseModule.java:50)

org.apache.shindig.gadgets.parse.ParseModule$DOMImplementationProvider$$FastClassByGuice$$a37f9102.newInstanc
e(<generated>)
After some investigation it seems to me that the problem is caused by NOT
deploying Cassandra in the integration test. In the normal runtime Cassandra
starts first, loads the jackson library which loads the
DOMImplementationRegistry class using the bootstrap classloader. In the
integration test, Cassandra is not started and Guice will try to load the class
using the bundle classloader instead.
