Refactoring inline methods leads to changes in access permissions

[provide a description of the issue]

Environment

Operating System: Windows11
JDK version: 17
Visual Studio Code version: 1.88
Java extension version: 1.29

Steps To Reproduce

1. select "originalMethod()"
2. click “Refacator-inline method”

class OriginalClass {
private boolean flag = false;
public synchronized void originalMethod() throws InterruptedException {
flag = true;
notify();
}

public void callerMethod() throws InterruptedException {
originalMethod() ;
}
}

refactoring result:

reason:
Missing "synchronized" keyword decoration, access permissions changed

使用提供的 Java 类复现 issue 中的案例，然后定位“Refactor-inline method”命令的实现和测试。跟踪内联过程中原始方法的 synchronized 修饰符是如何处理的；完成的标准是生成的代码保留原始的访问和同步行为。
