getShortStackTraceback to summary
public static Object getShortStackTrace()

Returns string representation of the stack trace of the current call without the call to the getShortStackTrace itself, and ignoring usually irrelevant calls to methods in sun. and java.lang.reflect packages. The stack trace ignores calls before and including the first org.jboss.resteasy method, hence it usually finishes with the method handling respective REST endpoint. Each line of the stack trace is prepended with "\n ".

Returns:Object

If the logger org.keycloak.STACK_TRACE is set to trace level, then returns stack trace, else returns empty StringBuilder
