8244281: test/jdk/com/sun/crypto/provider/KeyProtector/IterationCount.java fails with --illegal-access=deny

[Alan Bateman]

I need a reviewer for a small update to 
test/jdk/com/sun/crypto/provider/KeyProtector/IterationCount.java. The 
test accesses a private field in com.sun.crypto.provider from a VM 
launched by the test. The launched VM needs to be run with --add-open to 
open the package, otherwise the test will fail when illegal reflective 
access is denied by default.

-Alan.
