[9] Review request: 8150307: Some tests fail when run on JDK 9 due to use of -Djava.ext.dirs

[Kevin Rushforth]

Hi Dave,

Can you review the following?

https://bugs.openjdk.java.net/browse/JDK-8150307
http://cr.openjdk.java.net/~kcr/8150307/webrev.00/

It should be the last code change needed prior to switching to JDK 9.

Thanks.
