I had a look at your changes and I believe you have hit the right balance. I also like the fact plain `java.lang.Error` has been transformed into `java.lang.InternalError`. Also thanks for sanitizing the error code checks to match what `GetIfTable` and `GetAdaptersAddresses` are documented to return. I believe we are ending in a much better place. Please give me some time to import your patch and give it a round of testing. ------------- PR: https://git.openjdk.java.net/jdk/pull/5956
