I'm using maven and the maven-javadoc-plugin with the umlgraph-doclet to create javadoc for my project. The part from my pom:

```
<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-site-plugin</artifactId>

            <configuration>
              <show>public</show>

              <doclet>org.umlgraph.doclet.UmlGraphDoc</doclet>
              <docletArtifact>
                <groupId>org.umlgraph</groupId>
                <artifactId>doclet</artifactId>

              </docletArtifact>

              <useStandardDocletOptions>true</useStandardDocletOptions>

            <reportSets>
              <reportSet>

                </reports>
              </reportSet>
            </reportSets>
          </plugin>
        </reportPlugins>
      </configuration>
    </plugin>
  </plugins>
</build>

The images are generated and look fine, when building the javadoc with jdk1.6 they get automatically integrated into all javadoc pages. But when building with jdk1.7, the images still get created but are not inside the javadoc pages. Even when using the v5.4 from the official website, the javadoc is imageless. And the debug output of maven also don't give any clue. On top of that, there is no way of contacting one of the UmlGraph devs by mail.

Can anyone give me some advice here, or have some ideas how to fix that?

Update: version 5.6.6 is now on maven central. I built with JDK 7 and diagrams look ok.

```
<plugin>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>2.7</version>
    <configuration>
        <aggregate>true</aggregate>
        <show>private</show>
        <doclet>org.umlgraph.doclet.UmlGraphDoc</doclet>
        <docletArtifact>
            <groupId>org.umlgraph</groupId>
            <artifactId>umlgraph</artifactId>
            <version>5.6.6</version>
        </docletArtifact>
    </configuration>
</plugin>

```
I have the same problem. My guess is that it's this bug:
