Hi,

I have a new installation of Eclipse 3.3.1.1 Europa version.

Trying to use the debugger, I just get this:

org.eclipse.jdt.internal.junit.runner.RemoteTestRunner at localhost:50095
Thread [main] (Suspended (exception ClassNotFoundException))
ClassLoader.findBootstrapClass(String) line: not available [native
method]
Launcher$ExtClassLoader(ClassLoader).findBootstrapClass0(Str ing) line:
not available
Launcher$ExtClassLoader(ClassLoader).loadClass(String, boolean) line:
not available
Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line:
not available
Launcher$AppClassLoader.loadClass(String, boolean) line: not available
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not
available
Launcher$AppClassLoader(ClassLoader).loadClassInternal(Strin g) line: not
available

I have poked around with my classpath settings, but can't owrk out what's
wrong.

Can someone help please?

Thanks,

John

Try deleting the launch configuration for that JUnit and then let
Eclipse re-create it by right-clicking on the test class (or its
project) and choosing Run As...

Hope this helps,
Eric

Thanks for the suggestion.

I have just tried that, but got the same result.

I have some other tests, that used to work with the debugger with a
previous installation of Eclipse, but they don't work now.

JUnit is there in the classpath - something missing that I can't see.

Hi John. It might help to narrow the problem down to know if the problem
is limited to JUnit tests and / or limited to debugger sessions. Can you
do JUnit with Run As? Can you debug a non-JUnit program? Thanks. Mark

Hi Mark,

It's limited to debugger sessions. Whether it is JUnit or a nonJUnit
program makes no difference. I can't do Debug As, and have tried deleting
configurations in the Debug Dialog, so that Eclipse will generate a new
configuration, but that doesn't help. I can do Run As just fine.

Always the same error message.

Hi John. I notice you're javaw.exe is very new (14 Dec 2007). I'm using
jre1.6.0_01 from March. It might be worth a try to try an older JRE. You
can change this in Eclipse in Window / Preferences / Java / Installed
JRE's. HTH. Mark

Nope - that date is just the date I tried to run debug on a test class.

I am using jre1.6.0_03
