mediaReaderRandomAccessReaderClass issue with wowza restful api - api

Question

I am using WowzaStreamingEngine 4.4.1 at Ubuntu 14.04. I used restful api and created vod application (restful_vod) as in examples, it didn't work didn't stream vod files. That's why, I compare application.xml files of default vod application and restful_vod application. There is a difference between MediaReader properties. Default vod application has no property at there but restful_vod has below:
<MediaReader>
<!-- Properties defined here will override any properties defined in conf/MediaReaders.xml for any MediaReaders loaded by this applications -->
<Properties>
<Property>
<Name>randomAccessReaderClass</Name>
<Value></Value>
<Type>String</Type>
</Property>
</Properties>
</MediaReader>
When I removed randomAccessReaderClass named property, it started to work. I realized mediaReaderRandomAccessReaderClass parameter manage its value at restful api side. But I couldn't find a way to prevent adding it while using restful api. I tried not setting mediaReaderRandomAccessReaderClass value and also setting mediaReaderRandomAccessReaderClass false, null and empty string.
Is there any way to prevent adding it or a default working value for this?
Thanks.

You can set a default mediaReaderRandomAccessReaderClass by setting it as follows:
"mediaReaderRandomAccessReaderClass": ""
In your resulting Application.xml file, the MediaReader container would then be blank, which would indicate that it would use the default value:
<MediaReader>
<!-- Properties defined here will override any properties defined in conf/MediaReaders.xml for any MediaReaders loaded by this applications -->
<Properties>
</Properties>
</MediaReader>
A working REST API command to create a VOD file, for example, would look like this.
curl -X POST --header 'Accept:application/json; charset=utf-8' --header 'Content-type:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/testvod -d'
