I have several projects with a dependency hierarchy. I found the
enhancer to be fragile and it often would not enhance the classes. I
had to do a 'clean' to make it happen. I could not find the pattern to
when it failed to enhance. It never looped on me so you may be seeing
a different problem.
About 3 weeks ago I had had enough and turned off the Enhancer
builder (the plugin yelled at me). In its place I added an ant task
to do the enhancement. I derived the ant task statements from the
Datanucleus site. Since that time things have been very stable and
the enhancer always finishes its job.
This is the essence of the ant task:
<!--

<taskdef name="enhance"
classname="com.google.appengine.tools.enhancer.EnhancerTask">

<pathelement path="${appengine.tools.lib}"/>
</classpath>
</taskdef>

<pathelement path="${proj.dir.gen.cls}"/>
</classpath>
<fileset dir="${proj.dir.gen.cls}" includes="**/*.class"/>
</enhance>
</target>

<fileset dir="${proj.dir.war.lib}" includes="*.jar"/>
<pathelement path="${proj.dir.war.cls}"/>
</classpath>
<fileset dir="${proj.dir.war.cls}" includes="**/*.class"/>
</enhance>
</target>
It may be worth a try.
