from a comment on JDK-818262:
In the test SSLSocketEmptyFragments that came with this change we get 2-4 exceptions/errors like the one below.
This happens on Windows. Can we make the test more reliable (e.g. increase allowed timeouts or retry the inputStream.read operation) ?
Exception :

java.lang.RuntimeException: An error occurred running the test.
