Description

In our internal environment, there was a test failure while running SLS tests with Jenkins.
It's difficult to align the uncaught exceptions (in this case an NPE) and the log itself as the exception is logged with e.printStackTrace().
This jira is to replace printStackTrace calls in SLS with LOG.error("msg", exception).
