This will need discussion as to whether the JDK should put in retry loops to work around interference from virus checkers. I wonder if it possible to get any input from the Microsoft engineers on whether native applications are expected to do this or whether the issue here is actually a configuration issue or problem with a specific virus checker. If we are adding a workaround to the JDK then it will require much more broader changes that does proposed so I think more analysis and discussion will be required before deciding whether it is right to do anywhere here or not.
