Deion I want to export a function like this: <p dir="a

Hi! I think you have made a typo in your example, i suppose it is: <div class="hig

<a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/us

I've reproduced the error in a test project: <a href="https://github.com/jneira/eta-te

<a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/us

Hi! I think you have made a typo in your example, i suppose it is:

foreign export java "@static eta.example.MyClass.sayAnything" sayAnythingEta :: String -> IO ()
sayAnythingEta text = do
  putStrLn text
  return ()

I've just test something similar with lastest etlas and eta and it worked for me.
What do you mean with "java multi-thread environment"?

from eta.

@jneira Hello, jneira, thank you for your answer. Actually, my program is multi-threaded, I want to call this function in multi-threaded state. Just like this:

public static void main(String[] args) {
        ThreadPoolExecutor threadPool = (ThreadPoolExecutor) Executors.newFixedThreadPool(100);

        long t0 = System.currentTimeMillis();

        for (int i = 0; i < 10; i++) {
            threadPool.execute(new Thread() {
                @Override
                public void run() {
                     eta.example.MyClass.sayAnything("Hello eta.");
                }
            });
        }

        threadPool.shutdown();
        try {
            threadPool.awaitTermination(Long.MAX_VALUE, TimeUnit.MINUTES);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        long t1 = System.currentTimeMillis();

        System.out.println("Time: " + (t1 - t0));
}
