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

[Lance Andersen]

HI Sean,

I think the change looks reasonable and I would keep it focused on its current intent for zip files given the problem you were addressing.

The test also looks reasonable.  Did you give any consideration to throwing a SkippedException if posixAttributes are not supported?

Also remember to update your copyright year prior to pushing…

Best
Lance
