B4J Question error: lambda expressions are not supported in -source 1.7

[fhersof]

Hello please help,
In B4J when compiling I get the error shown in the photo, I'm using jdk 1.80_45, thank you very much.

Switch to OpenJDK 11.

I have tried with jdk 11 and the lambda problem disappears but some important libraries are affected for me, is it possible to revert this lambda to traditional code?

    public static void main(int intport) 
    {
        VpnServer myVPN = new VpnServer(intport);
        myVPN.listen();
    }
    ------
    ------
        public void listen()
    {
        new Thread(() -> {
            while(running.get() && (serverSocket != null) && serverSocket.isBound())
            {
                try { serviceThreads.add(new RequestHandler(serverSocket.accept())); }
                catch(SocketTimeoutException e1) { /* Nothing to do here */ }
                catch (IOException e2) { e2.printStackTrace(); }
            }
        }).start();
    }

This is quite bad Java code.

You can replace it with new Runnable() {
'let the Java IDE complete the interface.
}
