Simple Streaming and Rdkit

Hi everybody,

When I try to use some nodes of RDKit to clean a library (for instance salt stripping, canonicalization ecc… ) or to do a similarity search along with the Simple Streaming I got the following error:

java.lang.IllegalThreadStateException: The current thread is not taken out of a thread pool

I know that there are already a couple of threads on this since it is a known bug, but they all have been closed years ago without a solution.

What can be done about it?

My system is:

Windows 11

Knime 5.2.1

RDKIT 2023.09.2

Thank you so much for your help!
