The exception type and message check is additionally only added for Windows and the message check is very specific intentionally, to make sure we don't allow any `IOException` to result in the test passing. The usage of the `WSAECONNABORTED_MSG` has a precedent in `test/jdk/java/net/httpclient/HandshakeFailureTest.java`, so I think that should be OK in this test too.
