Starting with Ant 1.8.0 the text » more» has been added to the set of lines that will be filtered out from stacktraces if the filtertrace attribute has been set. When constructing the InputStreamReader, you can give the encoding as argument. For example, working class-by-class avoids confusion about whether an unannotated type means you determined that the default is desirable, or it means you didn’t yet examine that type.
