Hi. If you can edit launchers, you can see that  rhino jar is there as variable. So just remove it.
If you cant, then you have to buid ITW without Rhino.

I think for future ITW without plugin, to remove rhino from boot classpath is logical step, but can
not be immediate.

Itw currentl do not have  mechanism to exclude single jar from bootcp. Hearing your case, likely
worthy to implement. Any ideas?

Please try to edit your launcher (javaws(.sh) or javaws.bat) and try if it fixes your problem.
As ITW 1.8 have binary launchers, the filtering of deps in runtime isliekly necessary.


Are you on distribution build or bundled one? In distribution, you can try to remoe rhino from
system. On bundled, you can remoe rhino from directory with bundled libraries.
