JDK 9 RFR of JDK-8031201: Fix casting lint issues in java.net

[Joe Darcy]

Hello,

Please review the simple patch below to address
     JDK-8031201: Fix casting lint issues in java.net

(The various ObjectInputStream.GetField.get methods which have a default 
parameter, have an property-typed return value already.)

Thanks,

-Joe
