When creating an "exe" installer on Windows, AbstractBundler.cleanup() calls IOUtils.deleteRecursive() to delete the tmp directory. It can intermittently fail trying to delete the msi file.
JDK-8265078 noted that this caused large problems in the automated tests, which were addressed by modifying IOUtils.deleteRecursive() and by modifying the tests, but the underlying problem (sometimes not deleting the msi file) still exists, and should be addressed by this issue.

This may be related to JDK-8263135 and JDK-8264551, and also may be related by running antivirus software on the system.
