[zeromq-dev] Java to C++: junk appended to message?

And it works for any length of String, as long as I set the last byte
to 0. Thanks. (I misunderstood, thinking you meant 5 bytes isn't
valid, but 6 is).

Thanks again,

P.S. an additional "send" method in Java that takes a String and
converts it automatically before sending might be ok for Strings, but
I perhaps should have known this tidbit about strings anyway. Many
thanks again!
