java.io.IOException: Unable to open root Jar file - still, everything works nicely #347
Description
I just deployed a new version of my app in the test environment and went to look at the logs. I noticed that there are a huge stacktrace of warnings during boot.
I haven't noticed before because everything still works fine, and in my dev environment (I use IntelliJ has an IDE ) this stacktrace does not appear.
I took a look in the previous logs, and this is not an issue of RC2 only. At least in the latest snapshots it was happening too.
The stacktrace is the following:
13:24:39.908 WARN o.a.t.util.scan.StandardJarScanner - Failed to scan JAR [jndi:/localhost/WEB-INF/lib/mysql-connector-java-5.1.28.jar] from WEB-INF/lib

(... it keeps going for all jar dependencies)The app work normally, but I find this warnings with stacktrace quite weird, no?
Thanks.
