Ran into a StackOverflowError while letting this tail a file for a while (over 10 min). Log file was idle the entire time.

I called Tail like this

    def read(r: BufferedReader): Unit = {
        if (!Thread.currentThread().isInterrupted) {
            val l = r.readLine
            if (l != null) {
                log.info(s"read line: $l")
            }
            read(r)
        } else {
            r.close()
            log.info("read() Shutdown!")
        }
    }

val file: File = new File(logFile)
val r = new BufferedReader(new InputStreamReader(Tail.follow(file)))
val readerThread = new Thread(new Runnable {
                def run() {
                    read(r)
                }
            })

readerThread.setDaemon(true)
readerThread.start()

Hi Alex,

I can't figure out what is this good for. It allows for surviving log rotation and still keep the handle to the log file that is backed up. But at that point it makes no sense to keep reading such file, right ?

Wouldn't it make more sense if it was able to continue with reading the new file that was created after the old was rotated? So that it could feel like it is reading one file but actually it would be xth file that it is reading after surviving rotation.

Thank you, Jakub
