Bug while running Clustering with data 2 similarity operator

Hello RapidMiner Community,

i think i found a bug in the Data to Similarity operator.

I'm clustering some little data set (around 20k lines) and after updating to 9.0.003 the data to similarity operator doesn't work anymore.

While clustering without that operator enabled everything works fine, with that operator enabled RapidMiner takes itself around 97% of memory and the process i ran doesn't show up in the result history.

To verify that i'm not doing something wrong i tested following:
- Executing only the read database Operator   ---> works
- Executing the whole Process without data2sim ---> works

- Clustering numerical ID + numerical Value + data2sim ---> Bug
- Clustering nominal value + text + data2sim  ---> Bug
- Clustering Text with Text + data2sim ---> Bug

I attached the process-XML and the RapidMiner Logfile down here.

Thanks for any help in this case!

CPU: Intel Xeon Gold 6140 @2,3Ghz
RAM: 64GB
HDD: 1TB
Windows Server 2016 64Bit
