Describe the bug
Annotating a Java record with @Builder produces The constructor ... is undefined

To Reproduce
Use vscode-java 1.42.0 and with a project that uses lombok, simply annotate a record with @Builder.

package org.example;

import java.util.List;
import lombok.Builder;

@Builder
public record Example(List<String> list) {
}

This probably happens with any Lombok version because vscode-java 1.42.0 uses JDT-LS 1.47.0, which is using the latest JDT Core. Recently, JDT Core made some updates to records : eclipse-jdt/eclipse.jdt.core#3925 , eclipse-jdt/eclipse.jdt.core#3980 so likely that lombok needs to adjust some of its usage of JDT Core.
