RFR: 8328995: launcher can't open jar files where the offset of the manifest is >4GB [v6]

[Liam Miller-Cushon]

> This change fixes a zip64 bug in the launcher that is prevent it from reading the manifest of jars where the 'relative offset of local header' field in the central directory entry is >4GB. As described in APPNOTE.TXT 4.5.3, the offset is too large to be stored in the central directory it is stored in a 'Zip64 Extended Information Extra Field'.
