Error in Step 5 following tutorial for csv to xes
I tried to get the XESame example running with the given example files from the tutorial here: http://www.processmining.org/xesame/examples
However the conversion fails at Step 5 with the following console message:
2014-11-03 12:52:21: (PROGRESS) Starting step 1 of 5: initialization.
2014-11-03 12:52:26: (PROGRESS) Starting step 2 of 5: Extracting log info.

2014-11-03 12:52:27: (PROGRESS) Starting step 5 of 5: Converting Cache DB to XES.
2014-11-03 12:52:30: (ERROR) There was an error while trying to convert the cache database to an XES file.
2014-11-03 12:52:30: (ERROR) org.deckfour.xes.model.impl.XTraceImpl cannot be cast to org.deckfour.xes.model.buffered.XTraceBufferedImpl
2014-11-03 12:52:30: (WARNING) Cancelling execution! We were busy creating an XES file from the cache database.
2014-11-03 12:52:30: (NOTICE) Execution safely terminated
Steps to reproduce:
1) Fresh Windows 7 32bit system (with upgrades)
2) Install Java 7 (current version 1.7.0_71)
3) Start ODBC with admin priviledges
4) Set up ODBC connection as described in the tutorial (connection test button in XESame yields success)
5) Use default settings and execute conversion
I did try this on several machines, also with Win 8 64bit systems. Changing random settings did not seem to help. The path to the cacheDB and and the output location seem to be stuck at the defaults (I managed so alter one of them once, but haven't found a pattern how to do so).
Is this behaviour a bug or is there anything else I can try to get the example running?
