Configure logger in vertx 3
<p>I am using vertx 3.0 with spring boot. Now I am trying to config logger log levels, using below config:</p>

<p>JVM Arguments:</p>

<pre><code>-Dspring.profiles.active=dev 
-Dvertx.logger-delegate-factory-class-name=io.vertx.core.logging.SLF4JLogDelegateFactory 
-Djava.util.logging.config.file=logging.properties
</code></pre>

<p>logging.properties:</p>

<pre><code>handlers=java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=ERROR
com.sensegrow.level=ERROR
</code></pre>

<p>JAVA Class:</p>

<pre><code>package com.sensegrow.main;

@SpringBootApplication
public class Application{

    private static Logger logger ;
    public static JsonObject config;
    private static Vertx vertx;

    // Convenience method so you can run it in your IDE
    public static void main(String[] args) throws Exception 
    {
        logger = LoggerFactory.getLogger(Application.class);
        logger.trace("trace");
        logger.debug("debug");
        logger.info("info");
        logger.warn("warning");
        logger.error("error");
        SpringApplication.run(Application.class, args);
    }
}
</code></pre>

<p>Output:</p>

<pre><code>16:29:58.073 [                main] INFO  - com.sensegrow.main.Application           - info
16:29:58.076 [                main] WARN  - com.sensegrow.main.Application           - warning
16:29:58.076 [                main] ERROR - com.sensegrow.main.Application           - error
</code></pre>

<p>As log level for package com.sensegrow is error. Why I am getting Info and warn level logs.</p>
