Johan Compagner commented on HTTPCORE-724:
------------------------------------------
Ah i guess this line:
[httpcomponents-client/AsyncClientTlsAlpn.java at 5.1.x ·
apache/httpcomponents-client
(github.com)|https://github.com/apache/httpcomponents-client/blob/5.1.x/httpclient5/src/test/java/org/apache/hc/client5/http/examples/AsyncClientTlsAlpn.java#L60]
means really "java 9 and newer" not "older" right?
1 problem is that if you compile still against java 8 but people run your stuff
on java 17 (they can choose) then this is a bit of a problem
> org.apache.hc.core5.util.ReflectionUtils us using illegal reflective access

> Key: HTTPCORE-724
> URL: https://issues.apache.org/jira/browse/HTTPCORE-724
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Affects Versions: 5.1.4
> Reporter: Johan Compagner
> Priority: Major
>
> a basic example:
>
>
>
> {code:java}
> public class Main {
> public static void main(String[] args) throws IOException,
> InterruptedException, ExecutionException, NoSuchAlgorithmException {
> System.err.println(String.join(" ",
> SSLContext.getDefault().getSupportedSSLParameters().getProtocols()));
> try (CloseableHttpAsyncClient client =
> HttpAsyncClients.createDefault()) {
> client.start();
> SimpleHttpRequest request1 =
> SimpleRequestBuilder.get("https://www.google.com/";).build();
> Future<SimpleHttpResponse> future = client.execute(request1,
> null);
> // and wait until response is received
> SimpleHttpResponse response1 = future.get();
> System.out.println(request1.getRequestUri() + "->" +
> response1.getCode());
> };
> }
> {code}
>
>
> does not work under java 16 or higher
>
> in java 16 you can get around it by using:
> --illegal-access=permit
> but in java 17 that is not allowed anymore, that is ignored.
> if you run it with java 15 you will get:
>
> WARNING: Illegal reflective access by
> org.apache.hc.core5.util.ReflectionUtils$1
> ([file:/C:/workspace_master/HttpTest/lib/httpcore5-5.1.4.jar|file:///C:/workspace_master/HttpTest/lib/httpcore5-5.1.4.jar])
> to method sun.security.ssl.SSLEngineImpl.getApplicationProtocol()
>
> and after that line if i enabled wire logging everything goes different, (i
> think java 16/17 then just try todo http1.1)
>
