调研方向

Start with org.netbeans.modules.java.source.save.CasualDiff.java, especially treesMatch at line 3484 and matchTypeTest, then reproduce the class rename using a pattern-matching instanceof expression. Trace how the BINDING_PATTERN node is handled during refactoring. Done means renaming completes without the AssertionError and the reference is updated correctly.
