Bug#848018: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger

Hi,

First, thanks a lot for reporting.

Nailed it :

$ davmail /etc/davmail.properties
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/log4j/Logger
        at davmail.DavGateway.<clinit>(DavGateway.java:45)
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger
        at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

        ... 1 more
$ sudo apt install liblog4j1.2-java
$ davmail /etc/davmail.properties

We missed this because libmail-java brings in log4j in the classpath
but not the jar.
