> {{MetricConfig}}'s {{getInteger}} will always return the default value.
> The reason is, since it delegates to Java's {{Properties.getProperty}} which returns null if the type of the value is not {{String}}.
> h3. Reproduce
>  # Create a class {{MyReporter}} implementing {{MetricReporter}}
>  # Implment the {{open()}} method so that you do {{config.getInteger("foo", null)}}
>  # Start an {{ExecutionEnvironment}} with and give it the following Configuration object:
> {code:java}
> configuration.setString("metrics.reporters", "my");
> configuration.setClass("metrics.reporter.my.class", MyReporter.class)
> configuration.setInteger("metrics.reporter.my.foo", 42);{code}
>  # In {{open()}} the value of {{foo}} is null.
