StackOverflowError - Java 9 Build 181

Cross-posting to security-dev as this is more relevant to that list and 
bcc-ing core-libs-dev.

I think this might be an issue with the JavaWebStart SecurityManager not 
being granted the proper permissions. It is possible that the deployment 
policy files are not being loaded or there is some other subtle 
bootstrapping issue. It should not result in a recursive loop of course, 
but there may be a workaround.

In the meantime, can you send me more information, preferably a test 
case and a log file with -Djava.security.debug=all enabled? (The latter 
will help analyze the recursion and see what security checks are failing 
and for which ProtectionDomains). Also, have you tested this on builds 
earlier than b181?

Thanks,
Sean
