Flemming Boller commented on SUREFIRE-298:
------------------------------------------
Moving the junit test with jmockit out into build.xml(ant) and make maven2
antrun plugin start it seems to work until the surefire plugin gets updated.

> Problem using -javaagent
> ------------------------
>
> Key: SUREFIRE-298
> URL: http://jira.codehaus.org/browse/SUREFIRE-298
> Project: Maven Surefire
> Issue Type: Bug
> Components: classloading
> Affects Versions: 2.0 (2.2 plugin)
> Environment: Windows XP
> Reporter: Bård Dybwad Kristensen
>
> I try to run the JMockit framework in my tests to do some mocking of static
> classes.
> I supply the argLine arguments as follows (some spaces added to avoid
> smileys):
> <configuration>
> <argLine>-javaagent:D : \
> .m2\repository\jmockit\jmockit\0.83\jmockit-0.83.jar</argLine>
> <forkMode>once</forkMode>
> </configuration>
> This does not work. The problem is that the Mockit class is not able to find
> neither the class it is suppose to mock nor the class to use as a mock. I
> have made two small classes, Math and MockMath each with one similar method
> and one static String constant. My setup-method in the testclass is as
> follows:
> protected void setUp() throws Exception {
> super.setUp();
> System.out.println(Math.TEST);
> System.out.println(MockMath.TEST);
> Mockit.redefineMethods(Math.class, MockMath.class);
> }
> When I run this, the two System.out.printlns runs Ok, and prints what it
> should, but the Mockit class returns the following error:
> java.lang.RuntimeException: Failed to read class file for
> no.ergo.ec.vaktplan.MockMath

> before.
> If I do a mvn eclipse:eclipse and create an eclipse project, I can run the
> test class without any problems in Eclipse (with exactly tha same VM
> arguments as I use in the pom.xml)
> So I guess it is some issue with which classloader that loads the Mockit
> class when it is supplied as the instrumentation class via the -javaagent
> switch.
> Anybody experience any problems like this using the -javaagent switch?
> Any feedback would be greatly appreciated.
