It also works fine in 6.5M1.
Could you please attach the full exception? Also, I was not able to reproduce (I simply executed Run File on SpeedTest from the project and it worked OK), could you please provide some details on how exactly can this issue be reproduced? Thanks.
I can't find out more about the exception than this: init: deps-jar: compile: compile-test-single: Testsuite: SpeedTest Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0,172 sec Testcase: initializationError0(SpeedTest): Caused an ERROR Test class should have public zero-argument constructor java.lang.Exception: Test class should have public zero-argument constructor at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) Caused by: java.lang.NoSuchMethodException: SpeedTest.<init>() at java.lang.Class.getConstructor0(Class.java:2706) at java.lang.Class.getConstructor(Class.java:1657) Test SpeedTest FAILED C:\Projects\nio_charset\nbproject\build-impl.xml:614: Some tests failed; see details above.

Sorry, but I still cannot reproduce. This is what I did: 1. in /tmp: svn checkout https://java-nio-charset-enhanced.dev.java.net/svn/java-nio-charset-enhanced/trunk java-nio-charset-enhanced 2. Opened /tmp/java-nio-charset-enhanced in the IDE, opened Project/Properties, changed the platform to my default 1.6 3. Opened SpeedTest, ran the file (this used CoS). All tests passed. 4. Went to Project/Properties/Compile, disabled CoS. 5. ran SpeedTest again (without CoS). All tests passed. 6. "Test" whole project failed because of compilation errors in MapCalculator I am afraid I will need detailed steps to reproduce.
Hi Jan, I did a new try: 1. Installed build 200808120201 with new userdir. 2. Started build 200808120201 without import. + Tools->Plugins->Settings "Force install into shared directories" 3. Versioning->Subversion->Checkout https://java-nio-charset-enhanced.dev.java.net/svn/java-nio-charset-enhanced/trunk to \Projects\nio_charset_2\ (note: without last token "java-nio-charset-enhanced"). 4. Closed IDE to resolve broken references by copying old ..\config\Services\Platforms\org-netbeans-api-java-Platform\* ("JDK 1.6.0-b105 debug" is normal JDK 1.6.0-b105 + additional sources from /jdk1.6.0/src/j2se/src/share/classes/) 5. Copied also from old IDE: ..\config\Favorites\* ..\config\Toolbars\* 6. Started IDE. 7. Compiled SpeedTest.java (had to work around issue 143637). 8. Also compiled MapCalculator.java (wondering, I had no compile errors. Can you send me your errors?). 9. Ran SpeedTest (this used CoS). --> Had errors as discribed above. 10. Went to Project->Properties->Compile, disabled CoS. 11. Ran SpeedTest again (without CoS). --> Had errors as discribed above. 12. Opened Project->Properties, changed the platform to my default 1.6 13. Ran SpeedTest again (without CoS, default platform). --> Had errors as discribed above.
Created attachment 67174 [details] Platforms
One needs to use non-default platform to compile the MapCalculator (so the compiler is forked). I tried to comment-out the @RunWith(Parameterized.class) in SpeedTest, and the error appeared. So it seems that for some reason the annotation is not part of the .class file that is being executed. I checked the .class file produced by NetBeans, and it seems to contain the annotation.
> One needs to use non-default platform to compile the MapCalculator (so the compiler is forked). Reason: Issue 130352 Can anybody explain me what fork exactly means, and how it's enabled properly in contrast to this lousy workaround? It's annoying this additional non-default platform stuff. I always have to explain this to people using my sources after their first failed try. > I tried to comment-out the @RunWith(Parameterized.class) in SpeedTest, and the error appeared. I can reproduce this with my 6.5M1, but with 200808120201 the error appears always. > So it seems that for some reason the annotation is not part of the .class file that is being executed. I checked > the .class file produced by NetBeans, and it seems to contain the annotation. The "SpeedTest.class" produced by my 6.5M1 and 200808120201 are identical. But the error only occurs, if I run it by 200808120201. I will attach it for your evaluation. What other information can I give you?

Debugging output from ant might help (ideally from both NB6.1/NB6.5M1 and trunk with CoS disabled).
Sorry, is not possible because of issue 143945. Any further ideas?

As you see, now I was successful in logging the ant debug output.
Ok, I (think I) found out what is the problem. If one executes the tests in such a way that the build/test/classes is on the bootclasspath, but junit-4.1.jar is not (which is the default behavior of the java-nio-charset-enhanced project on Windows and NB6.5M2+), the RunWith annotation cannot be resolved and the test crashes (the class is apparently loaded OK, the annotation seems to be simply ignored). Having junit on classpath is (of course) not enough. Note: -the junit-4.1.jar has been moved from java2 cluster into platform* cluster (presumably to support simple tests). So the reference to "${netbeans.home}/../java2/modules/ext/junit-4.1.jar" in project.properties is not correct and is ignored. -the value of "run.test.jvmargs.xbootclasspath" property uses ';' as path.separator, which is not recognized on Linux (':' is used as path.separator on UNIX), so the value is invalid on Linux and the tests passes (because both the test classes and junit are loaded from the classpath). To reproduce on Linux, I had to replace ';' with ':' in "run.test.jvmargs.xbootclasspath" and "run.jvmargs" properties. I quick (although not completely correct) fix is to refer to junit as: "${netbeans.home}/modules/ext/junit-4.1.jar"
Wow, not easy to find. Very tricky. Thanks Jan. ... I've filed issue 144051.
Using ${path.separator} instead : or ; helps
