Sumit Sharma created AMQ-9661:
---------------------------------

             Summary: ActiveMQ client ja code is sending both TLSv1.2 and 
TLSv1.3 in the ClientHello message, even when TLSv1.3 is explicitly set using 
SSLContext.getInstance("TLSv1.3").
                 Key: AMQ-9661
                 URL: https://issues.apache.org/jira/browse/AMQ-9661
             Project: ActiveMQ Classic
          Issue Type: Bug
         Environment: We are configuring *ActiveMQ client classes* to use 
*TLSv1.3* explicitly by setting the {{org.apache.activemq.broker.SslContext}} 
as follows:

SslContext mqSslcontext = new SslContext();

mqSslcontext .setCurrentSslContext( 
javax.net.ssl.SSLContext.getInstance("TLSv1.3"))

However, during the {*}SSL handshake{*}, the *ClientHello* message sent by 
ActiveMQ still includes both *TLSv1.2 and TLSv1.3* in the 
{{supported_versions}} extension, instead of restricting it to *TLSv1.3.*

 
 * {*}ActiveMQ jars Version{*}: 6.1.5
 * {*}JDK Version{*}: JDK 17
 * {*}Operating System{*}: linux
