TestNg runner fails to start when socks proxy specified

[krmahadevan]

For some tests we need socks proxy and we specify it in the VM parameters:
-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=7777

After that we get the following error (tried different versions of TestNG (6.8,6.3.1):

java.io.EOFException
    at java.io.DataInputStream.readBoolean(DataInputStream.java:244)
    at org.testng.RemoteTestNGStarter.main(RemoteTestNGStarter.java:46)

The interesting thing that JUnit works just fine.
