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.

Daniel J rightly noted that the exception message could be localized by the OS and thus it's not a good idea to check for that message in the test. I've now updated the PR to remove the check of the error message. The test continues to pass on Windows and other OS, with this change.
