When I try to run my webapp under jetty configured with policy I get:
java.security.AccessControlException: access denied (java.util.PropertyPermission hu.prolan.slm.vaadin.Debug read)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:393)
No such file can be found under the unpacked webapp.
It might help to allow permission for it if I knew what this file is and where it comes from.
How about connecting a remote debugger to your Jetty and setting an exception breakpoint on AccessControlException?
Although I haven’t really worked with these in years, I would guess the offending call is System.getProperty(“hu.prolan.slm.vaadin.Debug”) in your code, and your configuration only allows getting the values of certain properties - see the javadoc for PropertyPermission.
