Compilation failure in dubbo-config-spring6 module with JDK 1.8 on the 3.3 branch

[oxsean]

Environment

• Dubbo version: 3.3
• Operating System version: Windows 11
• Java version: 1.8

Steps to Reproduce the Issue

1.Compile Dubbo using JDK 1.8, but compilation failure in the dubbo-config-spring6 module.

Example

Using the 3.3 branch.

Expected Behavior

Dubbo 3.3 should be able to compile successfully with jdk 1.8.

Actual Behavior

Compilation fails with the error message:"class file has the wrong version 61.0, should be 52.0".

Proposal

The root cause is that dubbo-config-spring6 requires jdk 17. We can use maven profile activation to include this module only when the jdk version is >= 17.
