[8u] RFR: 8221246: NullPointerException within Win32ShellFolder2

[Alex Kashchenko]

Hi,

Please review the backport of JDK-8221246 to 8u:

Bug: https://bugs.openjdk.java.net/browse/JDK-8221246

Original review thread: 
https://mail.openjdk.java.net/pipermail/awt-dev/2019-June/015273.html

11u changeset: 
https://hg.openjdk.java.net/jdk-updates/jdk11u-dev/rev/2f95ca679634

8u webrev: http://cr.openjdk.java.net/~akasko/jdk8u/8221246/webrev.00/

Patch does not apply cleanly because of the differences in import 
section, all other code changes, besides imports, are left the same.
