[m2] Switching XML Parsers?

I'm having trouble with some tests failing in Maven 2 when they work fine in 
Ant and Maven 1.0.2.

The problem (SaxParseException and NPE) happens way down in the XML Parser. 
(The test uses Commons Chain which uses Digester which uses...)

>From http://maven.apache.org/faq.html#unit-test-14 I get that 1.0.2 included 
an XML parser (Xerces 2.4.0) but 1.1 doesn't, which I assume is the case 
with 2.0.  I'm seeing org.apache.crimson in the stack trace.

How can I get Maven 2 to use Xerces, so I can tell whether that's the 
problem?  I'm not sure if I'm supposed to set something in Surefire, or 
whether this is a JVM level thing.

Thanks,

I'm using 1.4.2_09 and I'm pretty sure it was using Crimson, at least that's 
what I was seeing in the stack trace.

 I added the following dependencies, but it didn't help, I still get the NPE 
and SaxParseException and the tests fail under m2.  (Is this what you were 
suggesting?)

      <dependency>
         <groupId>xerces</groupId>
         <artifactId>xercesImpl</artifactId>
         <version>2.4.0</version>
         <scope>test</scope>
      </dependency>

      <dependency>
         <groupId>xml-apis</groupId>
         <artifactId>xml-apis</artifactId>
         <version>2.0.2</version>
         <scope>test</scope>
      </dependency>

Then I tried switching to Xerces 2.7.1, but couldn't find an xml-apis jar
containing org.xml.sax.ext.Attributes2 in the repository.  After putting the 
one
that came with the Xerces download in my local repository, it went back to
the NPE/SaxParseException.

I copied the artifacts that I'm building (shale-core and shale-test) from my 
m1 repository (the tests work fine under m1) to my m2 repository, just to 
make sure I wasn't missing something, but still no luck.

I do get a slightly better error message with Xerces 2.4.0, in that it has a 
column number instead of -1: "Error at (41, 47: null"

It's complaining about line 41, column 47, which is the end of the 2nd line:
    <action              name="first"
                       method="#{test.first}">

(The entire file is here: 
http://svn.apache.org/repos/asf/struts/shale/trunk/core-library/src/test/org/apache/shale/dialog/faces/dialog-config.xml )

What else can I try?

Thanks,

Adding a dependency on xerces (or another xml parser) should fix this.

I personally only had trouble with the Xalan shipped with jdk 1.5.
