A modern programming language that makes developers happier.

kotlinlang

I did this
```
    companion object {
        @ClassRule
        @JvmField
        val neo4j = Neo4jRule()
    }```
now I get this error:
&gt; org.neo4j.server.ServerStartupException: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@6778aea6' was successfully initialized, but failed to start. Please see the attached cause exception "io.netty.handler.ssl.SslContext.newServerContextInternal(Lio/netty/handler/ssl/SslProvider;Ljava/security/Provider;[Ljava/security/cert/X509Certificate;Ljavax/net/ssl/TrustManagerFactory;[Ljava/security/cert/X509Certificate;Ljava/security/PrivateKey;Ljava/lang/String;Ljavax/net/ssl/KeyManagerFactory;Ljava/lang/Iterable;Lio/netty/handler/ssl/CipherSuiteFilter;Lio/netty/handler/ssl/ApplicationProtocolConfig;JJLio/netty/handler/ssl/ClientAuth;[Ljava/lang/String;ZZ)Lio/netty/handler/ssl/SslContext;".

Can you please post the actual stack trace?
