Description

My code calls

ScriptEngine eng = ...

((Invocable)eng).getInterface(aValue, SomeInterface.class);

In case of an incompatible 'aValue', the ScriptEngine throws a ClassCastException, although it should return just null (" null if the requested interface is unavailable").

This behaviour changed after NB 11.3, and is present in NB 12.5 - should be fixed.
