Subject Cocoon3 build breaks if you add Saxon-HE
Date Sat, 08 Dec 2012 17:08:07 GMT
Hi all,

I was refactoring XSLTTransformer a bit (effort to get support for choosing XSLT processor)
and added Saxon-HE 9.4 to the classpath in cocoon-sax

      <dependency>
        <groupId>net.sf.saxon</groupId>
        <artifactId>Saxon-HE</artifactId>
        <version>9.4</version>
      </dependency>

So after a while I decided to run all unit tests again just to see if my refactoring already
broke some unit tests. But at that point I was pretty sure I only restructured code and enabled
options. So I was really surprised to find out I broke

ProfilingIntegrationTest.testSimpleGenerator()

So I wasted quite some time understanding what I broke and the asserts should pass so I did
not understand what was going on until I inspected the surefire reports. It seems by just
adding Saxon-HE to the classpath I already broke the build. And to be 100% sure I removed
Saxon as dependency and ran the tests again.  The tests just passed find.

The main question is: How come a Saxon class is used although nowhere we explicitly configured
to use saxon?
