Empty buffer from a bukkit sent packet (to forge)

Hi, i don't exactly know how to explain my problem, but   the thermos server sends a custom payload packet as a first byte: the packet discriminator, and after my string content. But this String appears empty at the receiving on my client forge modded.

Here is the code:

Thanks in advance! Don't hesitate if you need some additional code =)
