I am no expert, but in my own eyes, I would have avoided using:
1°) A series of 'if' which behavior might be clumsy
2°) Redirections which kind of 'cut the flow'

What I would have done:
1°) Defining all the log_format stuff at the http level: the sooner, the
better

2°) Replacing the if series with a map (also in http) like the following:
map $http_user_agent $language {
Java/* java
....
"" etc
default none
}

3°) Using the output of the first map as the input of two others to define
zone and burst amount, like:
map $language $zone {
java one
}

map $language $burst {
java 140
}

4°) Processing all the requests in the default location :
location / {
root html;
index index.html;

if($language != none) {
limit_req zone=$zone burst=$burst;

access_log /var/log/nginx/access.log $language;
proxy_pass https://example.com;
}

....
}

All that is not error-proof, coming straight outta my mind with no
testing... but you get the general idea.
