No thread safe way to create a Policy #46

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
With anti samy, there is no thread safe way to create a policy file.  The
Policy.getInstance(...) methods all read/write from the private _instance
variable without synchronization.  If two threads are creating policy files
(even with the same file/filename) there is potential for conflict, see
http://www.ibm.com/developerworks/java/library/j-dcl.html , in particular
the section on out of order writes.  

I think the _instance variable in Policy can be removed altogether.
