HostFileManager holds two effectively immutable objects - includes and excludes. These two objects can be safely published together using a volatile container instead of synchronizing for all mutators and accessors. This improves the concurrency while using HostFileManager. -- This message was sent by Atlassian JIRA (v6.2#6252)
