attr: java version: 21 & the latest cldk version from pip

I'm trying to do some analysis for repo on github: https://github.com/apache/dubbo
dubbo has 3939 java files with 21400 lines of code which is not that big

when I try to do

cldk = CLDK(language="java")
cldk.analysis(project_path="dubbo")

the analysis runs and didn't get back I tried to wait over 5 minutes and I didn't get any results,
knowing that I tried to run the same code on the demo repo from the readme and that works for me in like 3-6 sec

any fixes or suggestions?
