public class AppendTextBadgeSummaryActionConverter
extends RobustReflectionConverter

Makes AppendTextBadgeSummaryAction persist as a plain BadgeSummaryAction in build.xml, without touching Java's own serialization contract.

A writeReplace() method would do the same substitution, but it is honored by any Java serialization, not just Run.XSTREAM2: Pipeline's CPS interpreter persists a running program's local variables (including whatever a script assigned manager.createSummary(...) to) with plain ObjectOutputStream/ ObjectInputStream across every durability checkpoint. A writeReplace()-based shim would come back from that round trip as a plain BadgeSummaryAction too, so a script that called appendText(...) again after the controller resumed would fail with MissingMethodException - breaking in Pipeline the exact thing being fixed in freestyle.

Registering this as an XStream Converter instead keeps the substitution confined to Run.XSTREAM2: only marshal(java.lang.Object, com.thoughtworks.xstream.io.HierarchicalStreamWriter, com.thoughtworks.xstream.converters.MarshallingContext) is overridden, to write a plain BadgeSummaryAction's fields (with the same resolves-to attribute writeReplace() would have produced) in place of this class's own; RobustReflectionConverter.unmarshal(com.thoughtworks.xstream.io.HierarchicalStreamReader, com.thoughtworks.xstream.converters.UnmarshallingContext) is inherited unchanged from RobustReflectionConverter, so reading is unaffected either way. ObjectOutputStream never consults registered XStream converters, so CPS state keeps the real shim, with appendText intact, across every checkpoint.
