I have a Junit test that runs fine from the command line, but when I
try to run it from Ant, it fails. I am using Junit 3.8.1, and the
exclude.properties file in Junit.jar is as follows:
#
# The list of excluded package paths for the TestCaseClassLoader
#
excluded.0=sun.*
excluded.1=com.sun.*
excluded.2=org.omg.*
excluded.3=javax.*
excluded.4=sunw.*
excluded.5=java.*
excluded.6=org.w3c.dom.*
excluded.7=org.xml.sax.*
excluded.8=net.jini.*

The path element I am using in ant is:
<path id="test.classpath" >
<pathelement location="${lib.dir}/httpunit.jar" />
<pathelement location="${lib.dir}/junit.jar" />
<pathelement location="${lib.dir}/Tidy.jar" />
<pathelement location="${lib.dir}/js.jar" />
<!-- <pathelement location="${lib.dir}/xalan.jar" /> -->
<pathelement location="${test.dir}" />
</path>

The error is:
[junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0.651

Any suggestions are greatly appreciated.
