Package: tomcat8
Version: 8.0.28-1
Severity: normal
During Tomcat 8 restart I get warning:
org.apache.catalina.core.StandardContext setPath
WARNING: A context path must either be an empty string or start with a '/' and do not end with a '/'. The path [/] does not meet these criteria and has been changed to []
I filed bug in upstream with wrong assumption:
https://bz.apache.org/bugzilla/show_bug.cgi?id=58754
and got response that shown that Debian packagers make mistake in
/usr/share/tomcat8-root/default_root/META-INF/context.xml
file:
<Context path="/"
antiResourceLocking="false" />
Docs say:
https://tomcat.apache.org/tomcat-8.0-doc/config/context.html
If the context path is the empty string them the base name will be ROOT
(always in upper case) otherwise the base name will be the context path with
the leading '/' removed and any remaining '/' characters replaced with '#'.
Using "/" as path may result that context will not be deployed:
