StackOverflowError - Java 9 Build 181

[Tom Hood]

Hi,

I hit an infinite recursion loop probably related to PolicyFile that exists
in Java 9 build 181 for windows 64-bit.  It might be related to JDK-8077418
<https://bugs.openjdk.java.net/browse/JDK-8077418>

I haven't tracked down what is causing our webstart app to hit this problem
yet, but I thought I would let you know sooner than later.  Also, it
probably is not a problem for our particular application as I should be
able to set the security manager to null which I think/hope will bypass
this issue.  I will try today to reproduce it in our app so I can confirm
if setting security manager to null will work for us.

The stack looks like the following: (with many repeat stacks omitted)
