RFR: JDK-8308872: enhance logging and some exception in krb5/Config.java

Thu May 25 14:37:18 UTC 2023

There exists already some logging in krb5/Config.java (enabled by -Dsun.security.krb5.debug=true), this could be enhanced for easier analysis of problems. Additionally some exception(s) might be slightly adjusted.
