I get the following error-massage when I try to open a existing xls-file (that include some macros) and add some data to it in R with the package "XLConnect".
Error in .jcall("java/lang/Class", "Ljava/lang/Class;", "forName", cl,: RcallMethod: cannot determine object class

I'm working on a LINUX-Server, which I recently updated it. In addition updated R, RStudio and RShiny-Server. Everything worked before the Update. If I run the same Shiny script local on my Win10 PC evrything works fine.I googled a lot and can't find any solution to my problem. Can you guys help me?
Java version openjdk 11.0.16
Linux server, R, Shiny-Server and RStudio-Server newest version
Thanks for your help. Please be kind, I'm new with Linux systems and these things.
EDIT:
I'm tried R CMD javareconf and get the following output
consol output. When I run my Rscript again, I get the same error massage like described above.
