> Using WatchService in Tailer instead of polling
> -----------------------------------------------

> Key: IO-470
> URL: https://issues.apache.org/jira/browse/IO-470
> Project: Commons IO
> Issue Type: Improvement
> Components: Utilities
> Affects Versions: 2.4
> Reporter: Jeremiah Orr
> Labels: Java7, Tailer
> Fix For: 2.5

> Original Estimate: 24h
> Remaining Estimate: 24h

> 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 7.
> 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.
