Own Launch implementation doesn't see classes from other bundles [message #1062870]

I am writing an eclipse plugin with functionality distributed on some modules (core, util, ui etc). During implementing of new launch configuration (launch of course must call functionality from other bundles) for own project type I faced with the problem that this launch starts in new thread and a class that implements launch functionality don't see classes from other bundles and I have NoClassDefFaundError all the time.

I see that classes are loaded with different classloaders and this is OSGI specific behavior. I added necessary dependencies in MANIFEST files and eclipse shows me thats all ok and successfully build my plugins in workspace. But what happens wrong and why this doesn't work?

From your description I'm not sure what is your problem actually?
Why do you mention threads in the context of NoClassDefFoundError?
Perhaps you don't mean "new thread" but "new JVM process"?
I'm also don't understand whether the error occurs in the launch delegate or in the target application.
Perhaps also a stacktrace would help.

Error occurs in Launch delegate.

And I faced with the problem that some classes can not be found. The feeling that Eclipse caches classes since last start and adds only a change in the existing classes, but does not add new classes.
