--------------------------------------------------------------
I was having a similar problem and I think I have nailed down the interaction
(I don't have any insight into what's causing the problem, however).
Attached is a simple maven project that contains two tests and one suite. The
two tests are ExplodingTest, which throws a java.lang.NoClassDefFoundError
inside a static block, and PassingTest which has a number of tests that, well,
pass.
The suite combines the two tests together.
Running "mvn clean test -Dtest=Suite" demonstrates the unexpected behavior from
surefire: No xml reports are generated describing the outcomes of the tests in
{{target/surefire-reports}}
To fix update the JUnit dependency in the pom.xml from 4.4 to 4.8.1. Doing that
and rerunning the command results in an accurate xml test result report being
generated.
I hope this helps clarify the problem. It was certainly a pain to track this
down. Since Spring < 3.0 requires JUnit <= 4.4 my guess is that most who have
experienced the issue are using Spring. So while it may *seem* like a Spring
issue I'm guessing it is really a JUnit 4.4 issue.
Cheers,

> Key: SUREFIRE-500
> URL: http://jira.codehaus.org/browse/SUREFIRE-500
> Project: Maven Surefire
> Issue Type: Bug
> Components: classloading
> Affects Versions: 2.4.2
> Environment: maven 2.0.9 , linux/ubuntu, jdk-sun-1.5.0_13
> Reporter: Johan Romme
> Attachments: surefireTest.zip

> We are using maven-2.0.9 for some project using spring/hibernate.
> When I made an incorrect change to the spring configuration (or actually I
> removed a hbm.xml file that was still referenced in the spring config),
> maven/surefire failed with an NoClassDefFoundError on one of our abstract
> test classes (where the spring config was loaded). Running in debug mode (-X)
> or increasing log4j levels did not reveal more info as to the cause of the
> problem.
> After some time I switched back to maven-2.0.7, maven/surefire also failed
> but with a meaningfull stacktrace that pointed immediately to the cause of
> the problem.
> So I fixed the problem, switched again to maven-2.0.9, with a succesfull
> build as result.
