Classloader problem ?
Hi,
I've got a problem when I try to use UISpec4J for unit testing Swing based
applications.
Iv'e got a test class that extends UISpecTestCase. In IntelliJ, my test
works witout any problem. But, when I try to run my test by using Maven2, it
throws an exception.

###################################################################################################################
It seems to be a problem of classloader that comes from UISpec4J. I don't
know how it is managed by surefire. Perhaps it comes from this piece of code
:
##############################################################
private static void setAwtToolkitProperty() {
try {
Class.forName(WINDOWS_SYSTEM_DEFAULT_VALUE);
awtToolkit = WINDOWS_SYSTEM_DEFAULT_VALUE;
}
catch (ClassNotFoundException e) {
try {
Class.forName(UNIX_SYSTEM_DEFAULT_VALUE);
awtToolkit = UNIX_SYSTEM_DEFAULT_VALUE;
}
catch (ClassNotFoundException e1) {
throw new AWTError("Unable to locate AWT Toolkit");
}
}
}
##############################################################
Has anyone have any idea about the source of my problem ? and how to resolve
this problem ? Or can anyone explain how surfire manage classloader ?
Thanks.

I don't have fork or childDelegation set but are facing a similiar
problem in commons jci. The tests run just fine from within eclipse
but through maven/surefire I also get ClassNotFoundExceptions.
Do I see a pattern here?

Hi,
I try to have a simpler example to test ClassLoader when I run my tests with
M2. (in this example, I don't use UISpec4J) With this example, I always have
a kind of class not found exception.
Here is a part of my POM file :
<plugin>
<groupId> org.apache.maven.plugins
</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<forkMode>once</forkMode>
<configuration>
<childDelegation>true</childDelegation>
</configuration>
</configuration>
</plugin>
Here is the method of test class that I used :
public void testClassLoader() throws Exception {
System.setProperty("awt.toolkit", MyToolkit.class.getName());
Toolkit defaultToolkit = Toolkit.getDefaultToolkit();
assertNotNull(defaultToolkit);
System.out.println ("defaultToolkit.getClass()= " +
defaultToolkit.getClass());
}
The result by using IDEA IntelliJ :
################################################################
defaultToolkit.getClass() = class com.agf.MyToolkit
################################################################
But the result by using maven2 is different. I get this exception :
################################################################
testClassLoader(com.agf.MyTest) Time elapsed: 0.062 sec <<< ERROR!
java.awt.AWTError: Toolkit not found: com.agf.MyToolkit
at java.awt.Toolkit$2.run(Toolkit.java:828)
at java.security.AccessController.doPrivileged(Native Method)
at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:804)
at com.agf.MyTest.testClassLoader(MyTest.java:14)
################################################################
I think that surfire manage different ClassLoaders and the Toolkit is not in
the good ClassLoader. Can anyone confim that ? and explain me how to solve
this problem ?
Thanks,
Olivier
