Encoding issues on VDCs descriptions

[AdriMenendezM]

Description
VDC's description may have an encoding problem generating de XML file sent through the API. The Java library is not able to decode the file and sets the pullElements attribute to null.

The unhandled exception is:

[Fatal Error] :1:2519: Invalid byte 2 of 3-byte UTF-8 sequence.

To Reproduce
Set a VDC description with an accent mark, ie. "máquina", and make a request to the API to get the VDC pool from the Javalibrary.
