[Originally posted erroneously to the pact-js channel] I'm using pact-jvm version 4.3.7 on a Spring Boot project. Running provider tests with Spring Boot 2.7 works fine, but if I uprev to Spring Boot 3 the test fails with the following stack trace:

ANTLR Tool version 4.9.2 used for code generation does not match the current runtime version 4.10.1
ANTLR Runtime version 4.9.2 used for parser compilation does not match the current runtime version 4.10.1

I'm guessing that the problem is that an Antlr 4 runtime dependency has been introduced via an uprev from Hibernate 5 to 6 (itself triggered by the uprev from Spring Boot 2 to 3), but pact needs Antlr 3. Is there any way around this? tia

4.3.x and 4.4.x won't work with Springboot 3. See https://github.com/pact-foundation/pact-jvm/pull/1663

Thanks @uglyog - I will try out the beta!

Ideally, we can release the non-beta version when we know that there are no issues impacting people. Unfortunately, most people will avoid the beta versions, so we won't know what issues would be impacting people until we release the non-beta version. 😉

Lol 😆 I must be swimming against that tide, because I currently rely on betas for both pact-js and pact-jvm.
