             Summary: using log (String) in a GenericRecipientMatcher causes a 
java.lang.AbstractMethodError
                 Key: MAILET-92
                 URL: https://issues.apache.org/jira/browse/MAILET-92
             Project: James Mailet
          Issue Type: Bug
          Components: Base Mailets
    Affects Versions: 2.5
         Environment: Windows 7
            Reporter: Vincent Kirsch


I have a Matcher that extends GenericRecipientMatcher, that I wrote with a 
previous version (mailet 2.4 and mailet-base 1.1) of the mailets and that 
worked just fine.

With version 2.5 (using apache-mailet-api-2.5.0.jar and 
apache-mailet-base-2.5.0.jar), the calls to log (String) end up with the 
following exception in the spoolmanager log file):

java.lang.AbstractMethodError: 
org.apache.james.James.log(Lorg/apache/mailet/MailetContext$LogLevel;Ljava/lang/String;)V
        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

        at org.apache.mailet.base.GenericMatcher.log(GenericMatcher.java:148)

I'm using James 2.3.2, and placed the mailet jar files in SAR-INF/lib
>From what I could find, at startup James creates a 'work' subdirectory, wihch 
>contains earlier versions of the mailet jar files (mailet-api-2.3.jar and 
>mailet-2.3.jar) -  which most probably don't contain the log() with the 
>expected signatures.

Is there a way around it? Where do these libraries come from?
