Hello,  
i'm trying to parse some tomcat logs but i'm getting the following errors:

```
io/console not supported; tty will not be manipulated
Can't load log handler "1catalina.org.apache.juli.FileHandler"
java.lang.ClassNotFoundException: 1catalina.org.apache.juli.FileHandler
.....
Can't load log handler "2localhost.org.apache.juli.FileHandler"
java.lang.ClassNotFoundException: 2localhost.org.apache.juli.FileHandler
java.lang.ClassNotFoundException: 2localhost.org.apache.juli.FileHandler
.....

java.lang.ClassNotFoundException: 3manager.org.apache.juli.FileHandler
...

java.lang.ClassNotFoundException: 4host-manager.org.apache.juli.FileHandler
java.lang.ClassNotFoundException: 4host-manager.org.apache.juli.FileHandler

```

Can someone propose a way to fix this?  
Thanks in advance,  
Fotis

Where are you getting these errors? What does your Logstash configuration look like?

Hi Magnus,  
I managed to fix the issue.  
As it seems, I was using a very old version of logstash (2.3.2).  
I used the newest one and the issue was fixed!
