Hi,

Not had a very good look yet, but it appears we'll need to pass
defaultHistoryContent to getTargetStates as well, as it is another area
where the algorithm is skipping past some history elements without
considering their executable content. This diff passes test579 :
https://github.com/zjnue/hscxml/commit/4b9091470d3c7c1995e6b41900535e0437ec3eb4
Another test or 2 on the subject is probably a good idea.

Best regards,
Zjnue
