I have a large application used in a production environment. My tiles setup is complex, with many tiles per page. The application works great with the exception of one thing. After starting the server the first page load throws an exception, an error in
apache.commons.digester.Digester at line 789/Digester.getParser
It throws this:
UnsupportedOperationException:: This parser does not support specification "null" version null"
The amazing thing is, this error only happens on the first page load, all subsequent loads work just fine. Looking for help with this, let me know what info you need. Thanks in advance.
This is the nested stack trace:

I had this problem today so thought I'd add a post, the problem was because of AppSensor (actually its ESAPI 2.0GA dependency), which comes with two different versions of xerces in its includes (2.6.1 from xom depenency, and 2.8.1 from antisamy dependency), but 2.6.1 comes before 2.8.1 so 2.8.1 is not included and the exception happens.
Fixed by adding a 2.8.1 dependency just before the AppSensor dependency in my POM:
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.8.1</version>
</dependency>
<dependency>
<groupId>org.owasp.appsensor</groupId>
<artifactId>AppSensor</artifactId>
<version>${appsensor.version}</version>
</dependency>
