I get an InitilizationException when i try to process an annotation for a MapConverter subclass. Below is output of my testcast. com.thoughtworks.xstream.InitializationException: Cannot instantiate converter com.thoughtworks.acceptance.annotations.MapConverterTest$MyMapConverter : Cannot construct com.thoughtworks.acceptance.annotations.MapConverterTest$MyMapConverter, none of the dependencies match any constructor's parameters at com.thoughtworks.xstream.mapper.AnnotationMapper.cacheConverter(AnnotationMapper.java:431) at com.thoughtworks.xstream.mapper.AnnotationMapper.processConverterAnnotations(AnnotationMapper.java:264) at com.thoughtworks.xstream.mapper.AnnotationMapper.processTypes(AnnotationMapper.java:162) at com.thoughtworks.xstream.mapper.AnnotationMapper.processAnnotations(AnnotationMapper.java:134) at com.thoughtworks.xstream.XStream.processAnnotations(XStream.java:1440) at com.thoughtworks.xstream.XStream.processAnnotations(XStream.java:1451) at com.thoughtworks.acceptance.annotations.MapConverterTest.setUp(MapConverterTest.java:42) Below is a new testcase for the above reported problem Index: /home/chungonn/development/projects/xstream-trunk/xstream/src/test/com/thoughtworks/acceptance/annotations/MapConverterTest.java =================================================================== — /home/chungonn/development/projects/xstream-trunk/xstream/src/test/com/thoughtworks/acceptance/annotations/MapConverterTest.java (revision 0) +++ /home/chungonn/development/projects/xstream-trunk/xstream/src/test/com/thoughtworks/acceptance/annotations/MapConverterTest.java (revision 0) @@ -0,0 +1,67 @@ +/* + * Copyright (C) 2006 Joe Walnes. + * Copyright (C) 2006, 2007 XStream Committers. + * All rights reserved. + * + * The software in this package is published under the terms of the BSD + * style license a copy of which has been included with this distribution in + * the LICENSE.txt file. + * + * Created on 02.
