You're server is running on a headless machine (or JDK is started headless), with our X11 available. Our diagram-generation needs AWT, which needs a valid graphical environment.

If you want to avoid these warning, you can disable the diagram-generation in the engine, prgramatically on the ProcessEngineConfiguration:

setCreateDiagramOnDeploy(boolean createDiagramOnDeploy) {
or in the config XML:

<bean id="processEngineConfiguration"
    class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

    <property name="createDiagramOnDeploy" value="false" />
    …

The javascript-preview of the diagrams will work, though…
