---------------------------------------
Summary: Avoid stacktrace logging and NPE
Key: FELIX-6686
URL: https://issues.apache.org/jira/browse/FELIX-6686
Project: Felix
Issue Type: Wish
Components: HTTP Service
Affects Versions: http.jetty-5.1.8
Reporter: André Freyssinet
Hi,
When the Jetty service cannot bind the desired port there is an error message,
and that's perfectly normal. But could we but could we avoid printing a
stacktrace ?
Additionally this situation leads to a NullPointerException with the printing
of a second stacktrace.
These stacktraces can be useful in debug mode but are not desirable in
production.
