Moving up the gwtcoverage-1.4.61.jar seems to help a bit. However, now
I get the following error:
[ERROR] Failure to load module 'com.mycompany.myapp.Application.JUnit'

I'm using Java 1.5.0_16. Was this JAR compiled with 1.6?
I also tried using the emma-maven-plugin by installing the emma.jar
and gwtcoverage.jar as Maven dependencies and referencing them in my
pom.xml:
<dependency>
<groupId>com.mycompany.gwt</groupId>
<artifactId>gwtcoverage</artifactId>
<version>1.4.61</version>
</dependency>
<dependency>
<groupId>com.mycompany.emma</groupId>
<artifactId>emma</artifactId>
<version>2.0.5312</version>
</dependency>
However, code coverage #s seem to stay the same regardless. Next I'll
try adding them as plugin dependencies rather than as project
dependencies.
