[BUG] lose getter/setter method after compile

[wh1zper]

Describe the bug
using @getter or @Setter annotation, when similary but not same word defined as field in Java class, it loses some getter/setter methods after compile

To Reproduce

@Setter
@Getter
public class Test {

    private JSONObject jCReturnedData;

    private JSONObject jcreturnedData;

    private String mQType;

    private String mqtype;
}

after compiled, it loses the getter and setter methods of field of 'jcreturnedData' and 'mqtype'

Expected behavior
should retain all the getter/setter methods

Version info (please complete the following information):

• Lombok version 1.18.14

This is a duplicate of #2590. The problem is that lombok searches for existing methods without case sensitivity.
