JFlex is listed as compile (and therefore as runtime) dependency. If someone 
uses the Maven repository to fetch the binary Ontopia lib, JFlex is downloaded 
as well. This is unnecessary since JFlex is only used to create self-contained 
lexers which have no dependency on the JFlex jar.

Proposal: 
Remove
    <dependency>
      <groupId>de.jflex</groupId>
      <artifactId>jflex</artifactId>
      <version>1.4.3</version>
      <scope>compile</scope>
    </dependency>
from the pom

This is a minor issue, though.
