[BUG] [Java] Getter/Setter naming convention not followed in generated models

[karismann]

Description

When generating a client library, the getters/setters for a field pId are getPId() and setPId().
As per naming conventions, this is wrong :

This should be getpId() and setpId()

Steps to reproduce

Here also the automated getter and setter generated by IntelliJ for this property :

public class TestClass {

    String pId;

    public String getpId() {
        return pId;
    }

    public void setpId(String pId) {
        this.pId = pId;
    }

}
