[keycloak-user] silent ssl error in debug level

[Jukka Sirviö]

Hello,
Maybe not yet Jira, I would first like to know if this same issue is happening on anybody else, or am I just doing something silly here? JDK versions in use, are as follow:

-=-=-=-=-=-=-=-=-=-=-=-=
keycloak-saml-wildfly-adapter-dist-1.9.2.Final.zip --> java version "1.8.0_73" Java(TM) SE Runtime Environment (build 1.8.0_73-b02) Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
-=-=-=-=-=-=-=-=-=-=-=-=
keycloak-demo-1.9.2.Final.tar.gz --> java version "1.8.0_77" Java(TM) SE Runtime Environment (build 1.8.0_77-b03) Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
-=-=-=-=-=-=-=-=-=-=-=-=

Thus SAML authentication is working ok / normally. Using SSL (https) public addresses both with IDP and SP, along with signed & encrypted SAML assertions. Public certificates are good and ok!
