When I run Saxon 7.4,  a similar error occurs.

java.lang.NoSuchMethodError: net/sf/saxon/event/Emitter.endDocument()V
        at net.sf.saxon.event.ProxyEmitter.endDocument(ProxyEmitter.java:70)

net.sf.saxon.event.Emitter is an abstract class which implements
some interface where endDocument() is defined.
But net.sf.saxon.event.Emitter does not implement the metdod
itself.

I do not know which compiler the author of Saxon uses, but 
it may be Sun's javac of SDK 1.4.

In order to avoid this error,  I recompile Saxon using kjc
that comes with kaffe.
