API Definition

OpenAPI specification required to reproduce the bug:

openapi: 3.1.0

Actual SDK

The buggy SDK that is produced:

/**
 * This file was auto-generated by Fern from our API Definition.
 */

package types;

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonValue;
import java.lang.Object;
import java.lang.String;
import java.time.OffsetDateTime;

public final class Timestamp {
  private final OffsetDateTime value;

  private Timestamp(OffsetDateTime value) {
    this.value = value;
  }

  ...

  @JsonCreator(
      mode = JsonCreator.Mode.DELEGATING
  )
  public static Timestamp of(OffsetDateTime value) {
    return new Timestamp(value);
  }

  public static Timestamp valueOf(String value) {
    return of(value);
  }
}

Notice the method valueOf calling of(...) with a string argument.

Expected SDK

The expected SDK

 ...

  public static Timestamp valueOf(String value) {
    return of(OffsetDateTime.parse(value));
  }
}

I think this bug comes from here:

fern/generators/java/generator-utils/src/main/java/com/fern/java/generators/AliasGenerator.java

Line 168 in d8575c9

return CodeBlock.builder().addStatement("return of(value)").build();
