New Revision: 1653550
URL: http://svn.apache.org/r1653550
Log:
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=57473
Add more logging to WarWatcher, specifically checking for odd states like
non-existent files that were just listed by the filesystem, which suggests a
permissions problem.
Moved log strings into LocalStrings.properties
