I don't know anything about rosjava, but I just tested roscpp in both 1.0
and 1.1 with string lengths in the tens of thousands without any problem.
roscpp in 1.0 can crash if it receives a malformed serialized message, which
may be what's happening -- do you have a callstack? What nodes are
communicating? rosjava <-> roscpp?
