Note "." before file name extension has to be escaped to mean a
literal '.' instead of "any-character" pattern,
".*\.gif" etc.

I wonder why there are two getter methods for watchEnabled property in
FarmWarDeployer,
[[[
public boolean isWatchEnabled() {
return watchEnabled;
}
public boolean getWatchEnabled() {
return watchEnabled;
}
public void setWatchEnabled(boolean watchEnabled) {
this.watchEnabled = watchEnabled;
}
]]]

org.apache.catalina.ha.deploy.WarWatcher.check check cluster wars at
/my/watch/dir
Note that message says "/my/watch/dir", but the configuration above
uses "/my/listen/dir/".
What are access permissions for the directory and for the file. Is
there search permission on the directory, is the file readable?
E.g. if the directory is not readable File.listFiles() returns null,
but the code interprets it as an empty list, silently proceeding
further.
