[11u] RFR: 8250968: Symlinks attributes not preserved when using jarsigner on zip files

[Langer, Christoph]

Hi,

please review the 11u backport of JDK- 8250968: Symlinks attributes not preserved when using jarsigner on zip files. It is relating to and following up JDK-8218021: Have jarsigner preserve posix permission attributes for which I have just sent an RFR as well [0]. Both fixes are part of Oracle 11.0.10.

So, with JDK-8218021 applied, this patch goes in quite smoothly. Only a few trivial merge conflicts needed to be resolved, half of them were copyright year conflicts. Furthermore, JavaUtilZipFileAccess.java.rej is in a different package in JDK11.

The bug has a CSR attached which also was approved for 11-pool already.
