Winstone Configures Self-signed Keystore for SSL Authentication

Question

I create a self-signed key using

keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass password -validity 1360 -keysize 2048

Deploying the keystore using the Winstone servlet container using the option --httpsKeyStore=keystore.jks. When accessing with chrome, I get the following error:

The server has a weak, ephemeral public key Diffie-Hellman

ERR_SSL_WEAK_SERVER_EPHEMERAL_DH_KEY

Is there a way to overcome this problem by creating a keystore or configuring Winstone? I can access the site from the Firefox browser.
