Thanks Jeff , I noticed earlier that the BigDecimals I already had kept working. I swapped al other Numerics to BigDecimals with the javaTypeResolver and hurray al worked again.
Still it's strange that non BigDecimals work as Keys but not as values, A fact is that it is a very odd database and there's no support to be found. Thanks for the confirmation that my now working solution is the right way, Corne
