AuthenticationFailedException: Unauthorized

Hi,

I'm trying to schedule a job via http rest using the REST JAVA CLIENT ALPHA 5.5.0.1 but I always received this exception (AuthenticationFailedException: Unauthorized) in the last method 'scheduleReport(job);' 

I tested to make http calls using Apache libraries with an xml file job descriptor and a basic authentication and it was OK. I tested with POSTMAN too and the rest calls were perfect.

I don't know what is happening with the REST JAVA CLIENT given by Jaspersoft.

Could you help me someone? Thanks for all.
