[keycloak-user] Error while loading the application

[Pulkit Gupta]

Hi Bruno,

I am consistently able to reproduce the issue if I am using any version of
Xalan.
However if I exclude this transitive dependency then everything works fine.
I tried overriding the version of xalan to 2.7.2 but still getting the same
error.

*jar tf xxMyJarxx-SNAPSHOT.war | grep xalan*
*WEB-INF/lib/xalan-2.7.2.jar*


Not sure if I should open this as a bug with keycloak or there is some
other work around for this.

Regards,
Pulkit
