Test fails depending on network settings.

Depending on network settings 'testSendRequestSync' test fails or passes.

[http://stackoverflow.com/questions/1881546/inetaddress-getlocalhost-throws-unknownhostexception]:
It seems that InetAddress.getLocalHost() ignores the /etc/resolv.conf but only looks at the /etc/hosts file

This is changed in java 7 compare to java 6.
