java - 升级到 RestEasy 4.5.x 后出现 StackOverflowError

Question

从 4.4.2 升级到 RestEasy 到 4.5.2 后，我在返回带有实体 InputStream 的响应时遇到了 StackOverflowError。返回基本的 10MB 流失败。

使用非常基本的代码可重现错误:

@Path("/")
public class TestResource {

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    @Path("/{size}")
    public Response donwload(@PathParam("size") long size) {
        return Response.ok(new NullInputStream(size)).build();
    }
}

请求:

localhost:8000/1000000  ==> OK
localhost:8000/10000000 ==> StackOverflowError

我明白了:
