If you can get time to try to reproduce with a JDK 11 or 12 build then 
it would be useful. As things stand there are still issues with using 
lambda expressions in the checkPermission method [1] but I believe the 
other recursive initialization issues that arise with malformed policy 
files or lcating resources for exception messages have been resolved.
