Exception while parsing config file

Hi,

I am trying to use this with Graylog 2.0.1 but I'm getting the following error when I try to launch the input for JVM monitoring:

I have configured the input as follows:

"title": "FIDS JMX Input", "global": false, "name": "JMX", "content_pack": null, "created_at": "2016-05-19T12:54:10.685Z", "type": "org.graylog.inputs.jmx.JMXInput", "creator_user_id": "admin", "attributes": { "configLabel": "FIDS HTTP monitor", "configPassword": "", "override_source": null, "configHosts": "vtor-lx-tomcat-u01", "configType": "JVM", "configCustomFilePath": "", "configInterval": 1, "configPort": 12345, "configUsername": "", "configIntervalUnit": "SECONDS" }, "static_fields": {}, "node": "85f479de-dbd4-45c1-8434-6241186c0a42", "id": "573db772df62b961586eb8a3"

This worked when I tried it with Graylog 1.3.4.

Looks like some API broken in Graylog 2.0.0. I have raised an issue on graylog-server to track this.

This was due to wrong default value in the plugin. Fixed the same. download the latest release (1.0.1).
