[BUG] Eclipse doesn't find usages of extension-methods in "find references" nor rename-refactoring

[dstango]

Describe the bug
When using methods made accessible via @ExtensionMethod these usages of the methods are neither found by "References in Workspace" (Ctrl-G), nor are they changed when refactoring such methods' names.

To Reproduce

• Make some methods available via @ExtensionMethod:

  @ExtensionMethod(MyExtensions.class) // containing a static method foo(Object o)
  class AnyClass {
    void anyMethod() {
      Object o = new Object();
      o.foo();
    }
  } 
  

• Variations of the problem

  • "References in Workspace"
    • move cursor on foo
    • press Ctrl-G
    • Result: search for usages of foo() doesn't contain class AnyClass
  • "Refactor"/"Rename"
    • move cursor on foo
    • press Alt-Ctrl-R
    • type bar as a new name and press return
    • Result: method name gets changed in Class MyExtensions, but usage in AnyClass does not. Results in syntax error in class AnyClass.
  • Invocation from class MyExtensions
    • go to class MyExtensions
    • move cursor on foo
    • invoke one of the above operation
    • both operation don't find/change anything in class AnyClass

Expected behavior

• usages of foo() in class AnyClass should be found
• renaming of foo()'s name should affect usage in class AnyClass

Version info (please complete the following information):

• Lombok version: 1.18.26
• Eclipse: 2023-03
