Hi,
please oblige and review the change
http://cr.openjdk.java.net/~msheppar/8175325/webrev/
for the issue raised in
https://bugs.openjdk.java.net/browse/JDK-8175325
the scenario is that a MulticastSocket, bound to a wildcard address,
which has yet to have its NetworkInterface
set, will return a synthesized NetworkInterface for a
getNetworkInterface method call. The newly constructed
has no InterfaceAddress bindings instantiated, resulting in a NPE when
getInterfaceAddresses is invoked.
The fix initializes the bindings member variable with an empty array, as
per suggestion in the bug, and also,
for completeness, places a null check in the getInterfaceAddresses method.
There is a side issue here, relating to the synthesis of a
NetworkInterface for a MulticastSocket
bound to a wildcard address. This is somewhat dubious semantics, and
would seem to be worthy of review
at some stage in the future.
regards
Mark
