I am troubleshooting an issue where I have a java web application. The web application is deployed in Tomcat. The web application makes a call to the backend server using java.net.HttpURLConnection. I am facing an issue when this application is subjected to load test I receive the following exception for the calls I make from the application to the backend server, The error is SSL exception when I try to get the response code for my Http call, This happens if I use OpenJDK for 5% of the calls
openjdk version "11.0.2" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.2+7)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+7, mixed mode)

I have trouble shooted this issue by Changing parameters (heap size, garbage collection, JVM options, SSL connectors,cetificates) but it did not help. The findings is application works fine under same load test when Adpopt Open JDK is used
openjdk version "11.0.9.1" 2020-11-04
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9.1+1)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9.1+1, mixed mode)
Can I please get some pointers as to what I can check between OpenJDK and AdoptOpenJDK. I understand its difficult to point out an issue in this case.
The challenge here is that this application is shared with the customers and we mention we support Java 11 , so ideally it should give the same performance irrespective of AdoptOpenJDK or OpenJDK.
Any pointers to this issue will be appreciated.
Thank you.
