Hi,

Sorry that you are seeing this issue with CodeMix. Thank you for the error details.
CodeMix will work seamlessly with Java 11 in Eclipse 2021-09. We have known breaks with newer versions of Java/Eclipse. Please switch to Java 11 (edit the eclipse.ini and point the -vm to Java 11) and check if the issue still persists.

Please note that CodeMix has reached its end of life and MyEclipse 2021 is the alternative. For more details, please see: https://www.genuitec.com/products/codemix/end-of-life-notice/

We have a free, 30-day trail for MyEclipse. If it fits your requirements, we can convert your existing CodeMix license to a MyEclipse license at no extra cost.

Apologies for inconvenience caused. Please let us know if you have any further questions.

–Swapna
Genuitec Support
