Not really, but ...
Using Gump's build.sh as "./build.sh myrmidon-api -debug" with an
empty CLASSPATH, I get (snipped stuff):
lass org.apache.myrmidon.build.AntlibDescriptorTask loaded from parent loader
+User task: antlib-descriptor

So the AntClassLoader#initialize call succeds but the Class#newInstance
method fails. initialize will try to invoke a constructor that isn't
there and can probably only resolve classes that your class is known
to depend on.
You may want to add a no-arg constructor to AntlibDescriptorTask, I
bet there are some classes your xdoclet version needs missing from the
system classpath (remember build.sysclasspath is set to only).
In build.sh I have
export CLASSPATH=$CP:$JAVA_HOME/lib/tools.jar
export
CLASSPATH=$CLASSPATH:/home/bodewig/dev/gump/xml-xerces2/java/build/xercesImpl.jar
export
CLASSPATH=$CLASSPATH:/home/bodewig/dev/gump/xml-xerces2/java/build/xmlParserAPIs.jar

all of these do exist.
