<p>Hi Andreas,</p>
<p>we will investigate whether we can avoid requiring the
annotation.<br>

<p>Executing Graal JavaScript on a stock JDK is possible already
(without Graal as optimizing compiler), and we are working on a
fully-performant solution for JDK 11 (with Graal). Graal
JavaScript tries to be closely compatible to Nashorn, but it is
unrealistic that it ever provides 100% compatibility. Feedback
like yours helps us understand what users care about most.<br>

<p>Graal JavaScript is significantly faster than Nashorn on most
peak performance benchmarks (often orders of magnitude faster).
But please note the difference: Nashorn always compiles the
JavaScript code it executes to bytecode. Graal JavaScript requires
Graal as optimizing compiler to achive good performance. The setup
you are testing right now does not include Graal, so in your case,
JavaScript is only interpreted, thus you will experience a
performance impact.</p>
<p>Best,<br>
Christian<br>

I guess it’s the above. I can’t change the scripts as we have
hundreds of them on customer’s side. We use Nashorn as the
scripting engine for SwiftMQ Streams. Nashorn automatically
choses the right method without the need to annotate.</div>

<div class="">Adding the annotation is possible but can’t you
provide a kind of Nashorn compatibility mode? That would make
the transitioning a lot easier.</div>

<div class="">We use the scripting engine as an integral part of
