Rob Spoor created HTTPCORE-728:
----------------------------------
Summary: SSLIOSession uses SSLEngine.getApplicationProtocol()
which doesn't exist in all Java 8 versions
Key: HTTPCORE-728
URL: https://issues.apache.org/jira/browse/HTTPCORE-728
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 5.2
Reporter: Rob Spoor
We have a Renovate bot that upgraded the HttpClient version from 5.1.3 to 5.2.
Tests that were working before now started failing with the following message:
{code}Exception in thread "I/O server dispatch-1" java.lang.NoSuchMethodError:
javax.net.ssl.SSLEngine.getApplicationProtocol()Ljava/lang/String;
at
org.apache.hc.core5.reactor.ssl.SSLIOSession.doHandshake(SSLIOSession.java:429){code}
I've done a comparison between version 5.1.3 and 5.2, and this change is
causing the issue:
5.1.3:
{code}final String applicationProtocol =
ReflectionUtils.callGetter(this.sslEngine, "ApplicationProtocol",
String.class);{code}
5.2:
{code}final String applicationProtocol =
this.sslEngine.getApplicationProtocol();{code}
The cause of the issue is that this method is officially added in Java 9. From
https://docs.oracle.com/en/java/javase/19/docs/api/java.base/javax/net/ssl/SSLEngine.html#getApplicationProtocol():
{quote}Since:
9{quote}
It seems that this method is backported to Java 8, but not to *all* versions.
From
https://docs.oracle.com/javase/8/docs/api/javax/net/ssl/SSLEngine.html#getApplicationProtocol--:
{quote}API Note:
This method is defined in Java SE 8 Maintenance Release 3.{quote}
One solution could be to make users upgrade Java 8 to the latest version (our
build server currently uses version 1.8.0_221). However, that may not work for
everybody.
