EASE Rhino engine interferes with BIRT [message #1750400]

I have EASE 0.3 and BIRT 4.5 installed on Eclipse Mars.2. BIRT uses Rhino internally for scripted data sources. EASE is configured to use the Rhino engine.
When I open the script shell I get an exception (see below). This does not happen when EASE uses the Nashorn scripting engine. Both EASE and BIRT try to initialize the Rhino engine, but this can be done only once per session.

I am aware of this incompatibility between BIRT and EASE. To my knowledge it has been there from the beginning and happens for all combinations for BIRT and EASE. The way it is now I do not see how you can use these tools together in the same environment without interfering with each other as long as you need the rhino engine support. We both try to change the Rhino classloader, but only the firt one succeeds, the 2nd one is bound to fail due to the Rhino design. I am sorry to say but from my point of view there is nothing we can do against it. Only option for you would be to use the nashorn engine and skip Rhino entirely for EASE.
