When use HttpServer and set maxSize parameter for upload file, i got error: IllegalReferenceCountException: refCnt: 0, decrement: 1 #3740
Description
when use HttpServer and set maxSize parameter for upload file, i got error: IllegalReferenceCountException: refCnt: 0, decrement: 1
Expected Behavior
when upload file exceed maxSize limit, should without causing IllegalReferenceCountException.
and only causing HttpPostRequestDecoder$ErrorDataDecoderException: java.io.IOException: Size exceed allowed maximum capacity.
Actual Behavior
when upload file exceed maxSize limit, definitely causing IllegalReferenceCountException.
Steps to Reproduce
public class Main {
public static void main(String[] args) throws Exception {
DisposableServer server =
HttpServer.create()
.port(8080)
.httpFormDecoder(e -> e.maxSize(1024 * 1024 * 10))
.route(routes -> routes
.post("/upload", (request, response) -> {
return request.receiveForm()
.map(InterfaceHttpData::getName)
.collectList()
.map(e -> String.join(",", e))
.flatMap((Function<String, Mono<Void>>) s -> response.sendString(Mono.just(s)).then());
})
)
.bindNow();
System.in.read();
}
}run this java main class，and send request with multipart/form-data, and file size should exceed maxSize, then you will get IllegalReferenceCountException.
