Unable to instantiate AdjustPrecisionAndScale: Plugin class must have a no-args constructor, and cannot be a non-static inner class #111

Had a similar issue seting JAVA_OPTS ="-Xmx 2g -Xms 2g" on kafka connect container resolved it |
Na, that did not work. I still get the same errors. I added this ENV to my docker compose file. |

I'm having the same problem. I find the solution that @rizvnn suggested improbable.. For me, it's an issue of kafka versions.. I'm using kafka-connect-transform-common-0.1.0.58. I did some testing, and I found that it works for for kafka version 3.5.2, but not >=3.6.0, so I think the plugin might not support kafka >=3.6.0 at this time. |

Question for you all. Does the class still work? Looking at the code we have a default constructor on the static class. We do not have a default constructor on the implementation. I think we could just change the declaration of the implementation to abstract to fix it. |

Not sure if this works with newer kafka version as connect-utils uses kafka-connect-api 2.8.0. I will experiment with it. Stay tuned. |

@jcustenborder With kafka 3.7.0 and your suggested solution I get the following when using connect-utils-0.7.177.jar: java.lang.NoClassDefFoundError: com/github/jcustenborder/kafka/connect/utils/config/ValidEnum │ |
We dont use these: AdjustPrecisionAndScale transforms. We only use using AddPrefix from confluent, changeTopicCase from kafka-connect-transform-common transformers and they still seem to work even with the above errors. So it might be just a few classes that are affected. |

@jcustenborder I've updated my PRs following your suggestions: |

I also have this issue with Kafka Connect 7.6. Is there a lower version of kafka-connect-transform-common thats works with it ok ?

@jcustenborder @marcuslinke these warnings seem to be related and also starting to appear when we upgraded to Kafka Connect 7.7.0. This also shows that the same issues appear in the kafka-connect-json-schema plugin as well |

class must have a no-args constructor, and cannot be a non-static inner classerror for following classes:I am not using these transformers so i could ignore it. I am only using
AddPrefix,changeTopicCasetransformers.Is there a up coming release that will work with the new base image?
