Liberty Fails to Select Correct SSL Configuration When Multiple OutboundConnections Are Defined

[una-tapa]

Describe the bug
The correct outboundConnection is not selected when multiple outbound connections are configured under one ssl id.

Steps to Reproduce

• Create multiple outboundConnections under one ssl id.
• Make one of the outbound call
• Liberty seems to concatinate all aliases to lookup and fail to find the ssl configuration.

<ssl id="mySSL" keyStoreRef="myKeyStore" trustStoreRef="myTrustStore" securityLevel="HIGH" sslProtocol="TLSv1.2" verifyHostname="false" trustDefaultCerts="true">
  <outboundConnection host="test1.ibm.com" port="50001" clientCertificate="OUTBOUND_CERT1"/>
  <outboundConnection host="test2.ibm.com" port="50002" clientCertificate="OUTBOUND_CERT2"/>
  <outboundConnection host="test3.ibm.com" port="50003" clientCertificate="OUTBOUND_CERT3"/>
</ssl>

Expected behavior
The correct ssl configuration is selected.

Diagnostic information:

• OpenLiberty Version: [e.g. 21.0.0.8 - 21.0.0.10]
• Affected feature(s) [e.g. mpHealth-3.0]
• Java Version: [i.e. full output of java -version]
• server.xml configuration (WITHOUT sensitive information like passwords)
• If it would be useful, upload the messages.log file found in $WLP_OUTPUT_DIR/messages.log
