Hello Everyone Looks like this is a bug in wiremock when it can’t merge query parameters (e.g. http://<host>?NAME=R%83%69%83%78%83%43%83%59) that are not UTF-8 encoding, e.g. if there is a query parameter that is Windows-31J encoding, it throws the following exception: Could you please help? Http 400
Copy code
<head>
	<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
	<title>Error 400 Bad query encoding</title>
</head>

<body>

This is not happening in Record and playback mode (proxy request to the destination). It fails before hitting stub.

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?

@Tom I have raised the issue in the GitHub wit the repro steps https://github.com/wiremock/wiremock/issues/2313. Could you please also fix this bug in wiremock-jre 2.33.2? as i have been using java 8. Thank you.

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.

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?
t
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 😎.

@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.
