Put missing properties JdbcDatabaseContainer.createConnection

[ebyhr]

The existing Properties constructor at L266 creates an empty property list. We should explicitly call putAll method.

It makes little sense to have the properties constructed with info if we already add all its properties.

fix makes sense

public class TestProperties
{
    public static void main(String[] args)
    {
        Properties properties = new Properties();
        properties.setProperty("key1", "value1");
        properties.setProperty("key2", "value2");
        properties.forEach((k, v) -> System.out.println(k + ": " + v));

        System.out.println("--- After Copy ---");

        Properties newProperties  = new Properties(properties);
        newProperties.forEach((k, v) -> System.out.println(k + ": " + v));


        System.out.println("--- Defaults ---");
        System.out.println(newProperties.getProperty("key1"));
        System.out.println(newProperties.getProperty("unknown"));

    }
