Reduce the verbosity of error logs

Since V 1.7.1, I am getting very long error messages spanning over 30 -60 lines which are totally meaningless for me being not a java developer.

I would like to reduce the length of the error messages.
What is the best approach?

You can suppress the logging of stack traces by editing your logback.xml file and adding the %nopex conversion word. On the line

<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%-5level] [%-30.30logger{36}] - %msg%n</pattern>

You could change it to

<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%-5level] [%-30.30logger{36}] - %msg%nopex%n</pattern>

HI watou,
