RFR: 8218021: jarsigner strips the execute permission when signing a .zip file

[Seán Coffey]

Hi,

I'd like to reboot this jarsigner enhancement request[1]. I've removed 
the problem references to zip file name extensions. Instead, there's a 
new JDK implementation specific jarsigner option: -keepposixperms

https://bugs.openjdk.java.net/browse/JDK-8218021
https://cr.openjdk.java.net/~coffeys/webrev.8218021.v2/webrev/

regards,
Sean.
