The problem is solved and it was NOT Java3d!

I'll try to describe it.

We have a product, comprises of many plugins (jar files); I'm responsible just for one, with Java3d.
The first run of installed product writed down a file

configuration\org.eclipse.osgi\framework.info.1

This file contains the whole information about all paths, classpath, native libray path and much more.

And when I changed some paths in my plugin (I did this to change from Java3d_152 to Java3d_171), then built plugin, replaced plugin in the product and then run the product, the tool used paths not from new plugin but from

configuration\org.eclipse.osgi\framework.info.1

This explained my ClassDefNotFoundException;

Deletion of

framework.info.1

 before plugin replacement helped me to solve this problem;

Conclusion: OSGI-Behaviour!  
May be someone knows, how to change this behaviour e.g. with a flag, but this is a not a Java3d topic!

Thanks a lot!
