Depending on order of local classes in a JAR, using javax.lang.model.util.Elements to access enclosed elements of a module/package in an annotation processor may lead to `com.sun.tools.javac.code.Type.cloneWithMetadata` throwing `java.lang.AssertionError: Cannot add metadata to this type: METHOD` when loading representations of these elements:

```
package a;

import java.io.Serializable;

public class ProblematicClass implements Serializable {
public static <X> X myMethod() {
record B(String a){}
record C(@Nullable B b) {}
return null;
}
}
```

Affects JDK 25, 24, 23, but not 21. Did not test on 22.

Minimal reproducer: https://github.com/yrodiere/jdk-playground/tree/cloneWithMetadata-cannot-add-metadata
See README.md for instructions.

Originally uncovered by Christian Beikov while working on Hibernate ORM. Initial investigation and reproducer are his.

The reproducer mentions a second problem; I'm unsure if it deserves a dedicated report so please let me know if so.

Stack trace:

```
An annotation processor threw an uncaught exception.
