Subject [jira] [Commented] (IO-470) Using WatchService in Tailer instead of polling
Date Thu, 04 Jun 2015 23:41:39 GMT


Sebb commented on IO-470:

Note: code should never catch and swallow Throwable. Some exceptions must never be swallowed;
e.g. ThreadDeath.

> Tailer would benefit from using Java 7's WatchService to detect file changes instead
of polling at a set interval. Tailer could respond quicker to changes, and it would save the
system from constant polling. This of course would mean that commons-io would require Java
> I don't know what the future release plans are for commons-io; if there's an upcoming
version that will require Java 7, I'll happily make this change myself.
