> The tests.api.java.net.DatagramSocketTest test crashes on assert in DRLVM : Assertion `IsInstanceOf(env, obj, struct_Class_to_jclass(f->get_class()))' failed.
> The reason is that java.net.DatagramSocket.setReuseAddress(boolean) calls to
> PlainDatagramSocketImpl.setOption(int optID, Object val) with Boolean value, but underlying native code treats this value as Integer.
> Quickfix must be straightforward enough, but I inclined to blame the design of INetworkSystem.[set|get]SocketOption() as the actual root of the evil. The problem is that this API conceals the details of contract for particular options, and a client have to guess which type of value to pass. And the implementation is basically an ugly switch sorting requests out to setBoolSocketOption() or setIntegerSocketOption(), etc. Shouldn'te refactor this?
