Hi @phileo99 !

Are you able to provide a reproducible sample?

From the stacktrace alone, It looks like it's related to -addconfigurationdebugging; it seems that a superclass name is null. Are you using that option? If you remove the option does it work? Do you get any warnings in the log about missing classes?

[phileo99]

if I remove -addconfigurationdebugging then it no longer crashes. Also there are no warnings in the log about missing classes

also happy
