Csaba,
I do not think this is possible currently. Once the classpath has been
modified on the engine config, I do not believe it can be changed to
remove cp entries. It may be worth trying it on the task,
task.getAppContext().put..
but I do not think this will work.

One way to do this is to put your jars in the resource folder (set the
resource folder on the EngineConfig), then add the jar to the resources
tab in the report design. For example if I have two jars each with its
own implementation of the text report item event handler, I could add
jar1 to report1 in the resources tab and jar2 to report2. Then specify
the proper package.classname for the event handler in the report. Set
the resource folder in the engine config and run either report and the
proper jar should be picked up. I just tested this in the designer and
it worked fine.
