Shirish,
I am not familiar with VIPA interfaces, but I don't see any
documentation that describes allowable values for flags that could cause
the integer representing it to contain a negative value.
I'm not opposed to the source changes, I just don't see that they are
required. Can you please help explain?
Thanks,
-Chris.

Hi,
The return value from the getFlags() method in NetworkInterface.c is
interpreted in 2 ways.
- If the value is negative an Exception is thrown
- Else the return value is considered as the flag mask obtained via the
ioctl call.
In rare cases is it possible the value in the ifr_flags could be
negative. One such case is VIPA interfaces. any calls like isUp() on
such network interfaces would end up in a Socket Exception.
I have patch for this. Anyone would like to take a look ?
