I am trying to use Kotlin JSR 223 in multi-threaded environment. My assumption is same CompiledScript instance can be used from multiple threads at same time and create new binding when invoking compiledscript.eval function.
Below code throws exception:
CompiledScript compileScript1 = ((KotlinJsr223JvmLocalScriptEngine) scriptEngine).compile(“bindings["x"] as Int + 5”);
Bindings bindings1 = ((KotlinJsr223JvmLocalScriptEngine) scriptEngine).createBindings();
bindings1.put(“x”, 3);
System.out.println("Eval result : " + compileScript1.eval(bindings1));
CompiledScript compileScript2 = ((KotlinJsr223JvmLocalScriptEngine) scriptEngine).compile(“bindings["y"] as Int + 5”);
Bindings bindings2 = ((KotlinJsr223JvmLocalScriptEngine) scriptEngine).createBindings();
bindings2.put(“x”, 8);
bindings2.put(“y”, 5);
System.out.println("Eval result : " + compileScript2.eval(bindings2)); // Throw happens here …
throws

Note: If i use same binding instance for both eval, it works fine.
