I'm using commons-net to ftp a bunch of files around every night as a batch process.
It probably copies just under 1g. Over the course of that process I'll often get 2
or 3 thrown exceptions like so:
[java] java.lang.NullPointerException
[java] at java.io.BufferedInputStream.read(BufferedInputStream.java:279)
[java] at java.io.BufferedInputStream.fill(BufferedInputStream.java:183)
[java] at java.io.BufferedInputStream.read(BufferedInputStream.java:201)
[java] at
org.apache.commons.net.telnet.TelnetInputStream.__read(TelnetInputStream.java:140)
[java] at
org.apache.commons.net.telnet.TelnetInputStream.run(TelnetInputStream.java:464)
[java] at java.lang.Thread.run(Thread.java:536)
It doesn't happen at any specific time. It isn't a particular file size, I see it on
25k - 5m files. I also haven't seen any problems with the copied files. I've sort of
let this go since there seem to be no ill effects, but it's making me nervous.
Any ideas what this might be, or suggestions on how to troubleshoot it?
