03 / ORIGINAL ISSUE TEXT

apache/shenyu #6601 · read the original issue

## Description
Root forces 17 (`pom.xml:84`, `:727-728`) via active compiler config, so children's `maven.compiler.source=8` is overridden. Two *production* TCP modules ship POM metadata claiming Java 8 bytecode while actually emitting 17.

## Location
```
Production — shenyu-protocol/shenyu-protocol-tcp/pom.xml:29-30
shenyu-spring-boot-starter/.../shenyu-spring-boot-starter-plugin-tcp/pom.xml:29-30
Test — shenyu-integrated-test/pom.xml:56-57 + 6 child modules
```

## Impact
Misleading artifact metadata; if root compiler config ever moves to `pluginManagement`, these silently fall back to 8 and break on Spring Boot 3.x.

## Suggested fix
Remove the `maven.compiler.source/target` overrides; let root's `java.version=17` apply.
