Backward compatibility issue of overload resolution ambiguity

[heli-os]

issue starts with https://github.com/OpenFeign/feign/pull/2170

Many code snippets are used this way.

RetryableException(
    response.status(),
    RATE_LIMIT_EXCEEDED,
    response.request().httpMethod(),
    null, // Date type (original)
    response.request(),
)

However, this code will not work with that change.

1. get a compile time error

Overload resolution ambiguity: 
public constructor RetryableException(p0: Int, p1: String!, p2: Request.HttpMethod!, p3: Date!, p4: Request!) defined in feign.RetryableException
public constructor RetryableException(p0: Int, p1: String!, p2: Request.HttpMethod!, p3: Long!, p4: Request!) defined in feign.RetryableException

2. ambiguous what to do when we don't want to use retry.

• Just looking at the code in the IDE didn't work, so I came to repository.

Two solutions to solve this problem

it's not intuitive, and it creates more confusion.

// first solution
RetryableException(
    response.status(),
    RATE_LIMIT_EXCEEDED,
    response.request().httpMethod(),
    null as Long?,
    response.request(),
)

// second solution
val nonRetryable: Long? = null
RetryableException(
    response.status(),
    RATE_LIMIT_EXCEEDED,
    response.request().httpMethod(),
    nonRetryable,
    response.request(),
)

Suggest two things

1. fundamentally fix the overload resolution ambiguity.
   • need to ideation about how to fix it.
2. annotate how it should be written in the new constructor when don't want to retry.
   • What about adding it to a new constructor?
