Why do I get ERROR ting.server.rrs.importer.commands.CsvExportCommand - Unexpected exception in RRC?

If I export records to a CSV file within RRC, not all records will be exported and I see a lot of error messages in rm.log.

I can edit a record which was not exported, change one character somewhere and save. In next export it can be exported.

What is corrupt with my records? Or is something wrong configured? How can I debug?

I'm using V.3.0.1.4 on Windows 2008-R2/64bit with WAS 8.0.0.4/64bit and DB2 9.7.5/64bit

Here the full error message:
