Ah, then you have the larger problem of potentially being subject to the broken-ness.
Since I know you are under a time constraint, in the short term I would suggest reverting
07b79693af66812c02044c36f1eb2e7cc3cabe8c locally.
The larger issue is that ByteBuffer::align() is computing based on the alignment of
the char* internal to the ByteBuffer, as opposed to the start of serialization.
Since PVD supports serialization in multiple parts at the discretion of the sender,
this opens the possibility of unexpected padding being added to longer messages.
