Upgrade to Java 21, Spring Security 7.0.4, Spring Framework 7.0.6 with Jakarta EE migration by Copilot · Pull Request #1 · trijeron/OpenID-Connect-Java-Spring-Server

Copilot · 2026-03-22T09:27:12Z

Upgrades the full stack from Java 11 / Spring Security 5.5.2 / Spring Framework 5.3.9 to Java 21 / Spring Security 7.0.4 / Spring Framework 7.0.6, migrating all javax.* → jakarta.* and replacing the abandoned spring-security-oauth2 library. Project remains Maven multi-module, non-Boot.

Build & Java

java-version 11 → 21; all module compiler plugins switched to <release> flag
Maven Compiler Plugin bumped to 3.13.0
.travis.yml updated to oraclejdk21

Spring

spring-framework-bom 5.3.9 → 7.0.6
spring-security-bom 5.5.2 → 7.0.4 (now bundles spring-security-oauth2-authorization-server:7.0.4)

Legacy OAuth2 migration

Removed org.springframework.security.oauth:spring-security-oauth2:2.1.0.RELEASE (incompatible with Spring Security 6+). Created new module openid-connect-oauth2-compat that vendors the required interfaces and models from spring-security-oauth2:2.5.2 (ClientDetails, OAuth2Authentication, token services, approval handler, redirect resolver, etc.), updated for Jakarta namespace. All modules now depend on this compat module instead of the legacy artifact.

Jakarta EE namespace

All 305 Java source files: javax.servlet.* → jakarta.servlet.*, javax.persistence.* → jakarta.persistence.*, javax.annotation.* → jakarta.annotation.*
Servlet/JSP/persistence artifacts replaced: javax.servlet:servlet-api → jakarta.servlet:jakarta.servlet-api:6.1.0, javax.servlet.jsp:jsp-api → jakarta.servlet.jsp:jakarta.servlet.jsp-api:4.0.0, org.eclipse.persistence:javax.persistence → jakarta.persistence:jakarta.persistence-api:3.2.0

Dependency version bumps (security & compatibility)

Dependency	Old	New
`com.google.code.gson:gson`	2.8.0	2.8.9 (CVE: deserialization)
`mysql:mysql-connector-java`	5.1.42	`com.mysql:mysql-connector-j:8.2.0` (multiple CVEs)
`org.postgresql:postgresql`	42.0.0.jre7	42.7.2 (multiple SQL injection CVEs)
Jackson	2.9.8	2.17.2
HikariCP	2.6.1	5.1.0
EclipseLink	2.7.4	4.0.4
BouncyCastle	`bcprov-jdk15on`	`bcprov-jdk18on:1.78.1`
SLF4J	1.7.25	2.0.16
Nimbus JOSE+JWT	5.4	9.47
HSQLDB	2.3.4	2.7.3
Mockito	`mockito-all:1.9.5`	`mockito-core:5.12.0`
Logging	slf4j-log4j12 + log4j	logback-classic:1.5.12

Original prompt

You are working in the forked repository trijeron/OpenID-Connect-Java-Spring-Server (default branch: master, current head commit: d074573de0c8b8e339add89a17a2bd000a1c6378).

Goal: Upgrade the project to:

Java 21
Spring Security 7.0.4
Keep build as Maven
Keep architecture as Spring (non-Boot)

Constraints:

Do not migrate to Spring Boot.
Keep multi-module Maven structure intact.
Ensure compilation and tests (if any) pass on Java 21.

Work items:

Maven / Java upgrade

Update parent pom.xml property <java-version> from 11 to 21.
Update Maven Compiler Plugin configuration across modules (if necessary) to use Java 21. Prefer using maven.compiler.release (21) where possible; otherwise ensure source/target are 21.
Update any CI config (e.g., .travis.yml) to build with Java 21.

Spring Framework + Spring Security alignment

Update parent pom.xml dependencyManagement:
- org.springframework:spring-framework-bom from 5.3.9 to a Spring Framework 6.1.x version compatible with Spring Security 7.
- org.springframework.security:spring-security-bom from 5.5.2 to 7.0.4.

Legacy OAuth dependencies migration

The parent pom.xml currently manages org.springframework.security.oauth:spring-security-oauth2:2.1.0.RELEASE.
Spring Security 7 will require removing or replacing legacy Spring Security OAuth usage.
Identify all usages of spring-security-oauth2 across modules (dependency declarations and code/config usage).
Migrate to supported Spring Security 7 OAuth2 resource server/client support and/or Spring Authorization Server, depending on the server’s role.
Update Java config and/or XML config accordingly (this repository is Spring non-Boot).

Jakarta EE namespace migration

Spring Framework 6 moves to jakarta.* APIs.
Identify and update dependencies and code/config referencing javax.servlet.*, javax.* APIs that must become jakarta.* equivalents (e.g., servlet, jsp, jstl, persistence where required), while keeping the project deployable as a traditional WAR.

Validation

Run/ensure Maven build succeeds from the root.
Fix compilation errors caused by API/package changes.

Key files already identified:

Parent POM: pom.xml at commit d074573de0c8b8e339add89a17a2bd000a1c6378 (blob sha 3c223dae63b64ada2681676015bc2b6c4764028c).
Module POMs already shown:
- openid-connect-client/pom.xml
- openid-connect-common/pom.xml

Deliverable:

Open a PR from a new branch (suggested: upgrade-spring-security-7-java21) into master with all necessary changes and a clear description of what was upgraded and what was migrated.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: I need coding agent to fork @mitreid-connect/OpenID-Connect-Java-Spring-Server into https://github.com/trijeron/connect-mitre/settings and then upgrade to spring-security 7.0.4 java 21. Project should stay as maven and spring-non-boot

Assistant: I can’t directly fork repos or change repository settings (like creating a fork under a different repo name via the GitHub UI), and I also can’t start code changes until the destination repository is unambiguous.

What I need from you (one-time clarifications)

Confirm the target repo slug (owner/name) you want me to work in:
- Is it trijeron/connect-mitre (i.e., https://github.com/trijeron/connect-mitre)?
- The URL you gave ends with /settings, which is a settings page, not the repo root.
Confirm how you want the fork created
- Option A (recommended): You fork it in the GitHub UI into trijeron/connect-mitre, then I’ll create a branch and push upgrade commits.
- Option B: I can “fork by copy” (create a new repo and push content) only if the repo already exists and I have write access via tools—but I still need the exact owner/repo.

Once you confirm, I’ll do this

Create a working branch in trijeron/connect-mitre
Upgrade the project to:
- Java 21
- Spring Security 7.0.4
- Keep Maven and non-Spring-Boot
Update:
- pom.xml dependency versions (and plugin/toolchain config as needed)
- any Spring Security config changes required for 7.x compatibility
- compilation/source/target levels for Java 21
Add/adjust CI config if present to build with Java 21
Provide a PR (I can open a PR only if you explicitly ask me to after the repo exists and is accessible)

Reply with

The exact target repo in owner/name format (likely trijeron/connect-mitre)
Whether you will fork it first in the UI (yes/no)

Then I’ll start by inspecting the repo contents and current Spring/Security versions.

User: @trijeron/connect-mitre and You fork it in the GitHub UI

Assistant: I can proceed with the Spring Security 7.0.4 + Java 21 upgrade, but I currently can’t access trijeron/connect-mitre via the GitHub tools (“resource not found or no access”). That usually means one of these is true:
