After searching a little more (also bugs.java.com) I realized that my testcase
can be improved, here a cleaner version, that still shows the same problem:
package fileevent;
import static java.nio.file.StandardWatchEventKinds.ENTRY_MODIFY;
import java.nio.file.FileSystem;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.WatchEvent;
import java.nio.file.WatchKey;
import java.nio.file.WatchService;
public class Testcase {
public static void main(String[] args) {
try {
Path dir = Paths.get(args[0]);
FileSystem fs = dir.getFileSystem();
WatchService watchService = fs.newWatchService();
WatchKey watchKey = dir.register(watchService, ENTRY_MODIFY);
for (;;) {
for (WatchEvent<?> event : watchService.take().pollEvents()) {
WatchEvent.Kind<?> kind = event.kind();
if (kind == ENTRY_MODIFY) {
@SuppressWarnings("unchecked")
WatchEvent<Path> ev = (WatchEvent<Path>) event;
Path file = ev.context();
System.out.println("File-Changed: " + file);
}
}
watchKey.reset();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
bugs.java.com showed no interesting entries for my problem (searched with
keyword: WatchEvent)
If you think I should open a bug there I'll do so, however I have opened a bug
quite some time ago and never heard anything back from the oracle guys ...
Best regards
Stefan
