java.sql.SQLRecoverableException: IO Error: Connection reset by peer, Authentication lapse

Original post is here eklausmeier.goip.de/blog/2019/01-19-java-sql-sqlrecoverableexception-io-error-connection-reset-by-peer-authentication-lapse.

I encountered the following error, when I wanted to connect to Oracle v12.2.0.1.0 database with Java 1.8.0_192-b26:

java.sql.SQLRecoverableException: IO Error: Connection reset by peer, Authentication lapse 321631 ms.

This was unexpected as the same program did run absolutely fine on another Linux machine. Program in question is

import java.sql.Connection;
import java.sql.SQLException;

import oracle.jdbc.pool.OracleDataSource;

public class OraSample1 {

        public static void main (String argv[]) {
                System.out.println("Starting...");
                try {
                        OracleDataSource ds = new OracleDataSource();
                        ds.setURL("jdbc:oracle:thin:@nuc:1521:orcl");
                        Connection conn=ds.getConnection("c##klm","klmOpRisk");
                        System.out.println("Connected");
                } catch (SQLException e) {
                        System.out.println(e);
                }
        }

}

Solution: Add the following property setting to command line

java -Djava.security.egd=file:/dev/urandom OraSample1
