AssetCAT xls conversion database read error

Hi Tom,

I added some assets to AssetCAT and wanted the XLS export to be converted into csv using DBConvert, however I get an Java related error msg.:

"Message:
java.lang.ClassCastException: class java.lang.String cannot be cast to class java.time.LocalDate
(java.lang.String and java.time.LocalDate are in module java.base of loader 'bootstrap')
Level:
SEVERE

Last week I processed several changes within BookCAT and that went fine, so I doubt if there is something wrong with Java on my PC although I don't know this for sure of course.

I use the current version of DBConvert, 8.6 and the Java Runtime Environment 8 update 471.
Can you give me an advice?

Thanks in advance & greetings,
René
