Issue while upgrading application from Stack2 to Stack3

[Manu2516789]

Hi all,

We are trying to upgrade Java applications from Stack2 to Stack3 in our cloud foundry environment
The app uses buildpack version 4.16.1 in both stacks for now.
We have a user provided service connected to the app which is AWS MySQL RDS (5.7.mysql_aurora.2.09.2) version.

This app on stack2 works fine without issues while connected to the user provided service.
But when changing the app from stack2 to 3 with same buildpack gives the error as below while connecting to the RDS :

Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
2022-09-02T14:17:26.11+0200 [APP/PROC/WEB/0] OUT at sun.security.ssl.HandshakeContext.(HandshakeContext.java:171) ~[?:1.8.0_312]
2022-09-02T14:17:26.11+0200 [APP/PROC/WEB/0] OUT at sun.security.ssl.ClientHandshakeContext.(ClientHandshakeContext.java:103) ~[?:1.8.0_312

What changes are done for the same buildpack version but in different stacks which is causing this issue?

When I update the user provided service with the jdbc url with useSSL=false it works in stack 3.

What change can be done in the app and where so tht it can connect to the RDS in stack 3 over TLSv1.2?

We tried:  (-Dhttps.protocols=TLSv1.2 -Dhttps.cipherSuites=TLS_RSA_WITH_AES_256_CBC_SHA256 -Ddeployment.security.TLSv1.2=true ) but without success.
Tried with some spring parameters(server.ssl.enabled-protocols=TLSv1.2, server.ssl.enabled=false, server.ssl.enabled=true) but did not work.

Please let us know what could be the cause and solution for the issue?

The sample app is spring-music which we are using now for testing and trial.
