Socket.setTrafficClass() on Mac OS X

Hi all,

I have TCP code which works fine on Linux, but fails on Mac OS X (java 1.5.0_07-87). In particular, the setTrafficClass below (the hex number is IPTOS_THROUGHPUT) throws a IOException with the following error:

upload: Invalid argument

[java] java.net.SocketException: Invalid argument

[java]at java.net.PlainSocketImpl.socketSetOption(Native Method)

[java]at java.net.PlainSocketImpl.setOption(PlainSocketImpl.java:264)

[java]at java.net.Socket.setTrafficClass(Socket.java:1211)

byte[] address = isa.getAddress().getAddress();

if (address.length == IPv4_INADDRSZ){// IPv4

s.setTrafficClass(0x08);

}

Any idea?

Thanks,

Michele
