Notes 6.0.2 crashes while using Notes-API and DXL toolkit

Hi all,we used the DXL toolkit for import and export documents with a Notes client R5, but after upgrading Notes to R6.0.2 Notes terminated with a NSD message after connecting to the database and reading the documents content. Does anyone know if the function calls have changed in the notes.jar and the dxltools.jar? Or is the DXL toolkit not running with Notes 6.0.2?

TIA, Chris
