Alex Nistico ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYmJmM2Y4NjYw... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16935?atlOrigin=eyJpIjoiYmJmM2... ) HHH-16935 ( https://hibernate.atlassian.net/browse/HHH-16935?atlOrigin=eyJpIjoiYmJmM2... ) Hibernate cdi extension Regression introduced by HHH-16096 ( https://hibernate.atlassian.net/browse/HHH-16935?atlOrigin=eyJpIjoiYmJmM2... ) Change By: Alex Nistico ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Commit a742f5e caused an inversion of options which means that CDI extensions are disallowed when the configuration actually enables them. !image-20230714-012531.png|width=1747,height=952! The picture shows the problem in detail, but I think that a ! has been missed in the disableExtensionsInCdi() method. I also left a comment in the diff view. As a workaround you can could setup {{hibernate.cdi.extensions=false}} to actually allow them , but it’s both confusing and could have other unintended consequences.
