In general, yes. The more lines of code per feature, the more bugs per feature. Also, the guarantees you get from a typed language like Java does not seem to prevent bugs to a meaningful degree. Probably things like programming culture associated with a language is more important, like a strong preference for testing.

This is an interesting study on programming languages' effect on software quality: https://web.cs.ucdavis.edu/~filkov/papers/lang_github.pdf

I wonder if everyone actually does initial testing and bug fixing after committing, because otherwise any effect of programming language choice might be gone before the code reaches the commit logs.

I'm not sure it makes sense to consider code correctness separately from productivity. You can probably get code written in any language to roughly similar levels of correctness. But how much work does it take to get there? That's what I'm really interested in.
