The file header returned by jar.ManifestFileContents had unset date and mode fields. The unset date field resulted in the "Last Mod Time" field in the zip file being set to 0, which OpenJDK 9's jar implementation treats as an error: java.time.DateTimeException: Invalid value for MonthOfYear (valid values 1 - 12): 0 Bug: 67095392 Test: zipdetails out/host/linux-x86/framework/tradefed.jar Change-Id: I0a818d57420f5e5de57e8ff57791951c1b538443
