Due to the limitations of in-process handling, an intermediate dump file is written during exceptions. The data is streamed to a file using only in-process safe methods. The file format is similar to binary JSON, supporting keyed properties, maps and arrays. - Property [key:int, length:int, value:intarray] - StartMap [key:int], followed by repeating Properties until EndMap - StartArray [key:int], followed by repeating Maps until EndArray - EndMap, EndArray, EndDocument Similar to JSON, maps can contain other maps, arrays and properties. Once loaded, the binary file is read into a set of data structures that expose the data, maps and arrays.
