描述
By utilizing Go to References of static method I got error back.
Environment
- Operating System: Windows 11
- JDK version: 21
- Visual Studio Code version: 1.94.2
- Java extension version: 1.35.1
Steps To Reproduce
- Download and open test.zip
- Go to DemoApplication
- Find all references for public static Top of(One one), it will say no references found
However for method meta() in the same claas, DemoApplication, it will find references.
The error below happened on a project that I have no liberty of sharing. Hope it might be helpfull.

调研方向
在 Visual Studio Code 中，通过对 DemoApplication 的 public static Top of(One one) 方法使用 Go to References，复现使用 test.zip 时的失败。从 ReferencesHandler.search 和 stack trace 中列出的 JDT 搜索类开始，尤其是 MethodLocator 和 IntersectionTypeBinding18；当能够在不抛出 UnsupportedOperationException 的情况下返回引用时，即表示完成。
