Thank you for your reply. I created a repository that demonstrates the issue.
https://github.com/tzahifadida/test-chunked Currently it is set to 10.1.25 and fails. If you change it to 10.1.19 (in the pom.xml <tomcat.version>10.1.19</tomcat.version>) it will succeed. It should show 5 postings and not 1 in the output. The test can be run with “mvn test”. The output of the tcpdump is the same for both. The success dump and output (you can see the deltas are greater than 0 indicating they were received one by one): 2024-08-13T11:39:29.873+03:00 INFO 9753 --- [ Thread-1] o.s.boot.SpringApplication :
