The patch you inlined adjusts comments and fixes the issue with the test on Windows but it's hard to see everything (like getting JarFileSystem consistent with ZipFileSystem and I think whether we should rename getEntry0 because it looks strange that this is not private).

Sure I can refresh the webrev today.  I didn’t rename getEntry0 because that name is in ZipFileSystem and I assume it was chosen, instead of getEntry, for a reason.  Perhaps Sherman can shed some light on that.  The reason that it is not private is because JarFileSystem invokes ZipFileSystem.newInputStream, and that invokes getEntry0.
