8244283: test/jdk/sun/net/idn/TestStringPrep.java fails with --illegal-access=deny

[Alan Bateman]

I need a reviewer for a small update to 
test/jdk/sun/net/idn/TestStringPrep.java  The test locates 
sun/net/idn/uidna.spp in the java.base module so it needs sun.net.idn 
opened for this to work when illegal reflective access is denied by default.

-Alan.
