Hi < Jackie chen> thanks for flagging this It looks like this is probably a bug so please could you raise an issue in GitHub with the repro steps

Jackie chen · Answer

< Tom> I have raised the issue in the GitHub wit the repro steps Could you please also fix this bug in wiremock jre 2 33 2 as i have been using java 8 Thank you

Tom · Answer

Thanks for raising this < Jackie chen> Unfortunately we re not doing any more releases of 2 x now as we can t update a number of key dependencies due to their being Java 11+ and consequently we get a flurry of security scanner CVE errors sent our way if we attempt it There is now a Testcontainers Docker edition of WireMock 3 x which will work with Java 8 so it might be worth trying this out once we ve shipped the fix

Jackie chen · Answer

Hi < Tom> i am using wiremock jre8 2 33 2 in my maven springboot project which is compatible with Java 8 is there a way to include WireMock 3 x in my maven project that is still compatible with Java 8

Tom · Answer

Not by directly adding it to your dependencies but you can do it by running the WireMock 3 x server via Testcontainers which at the moment does still support Java sunglasses

< Tom> i got it is there a workaround on this issue i tried using StubRequestFilter to change the non utf8 encoding parameter but the exception is still thrown i would like it to match stub data somehow
