Tomcat "Failed to scan JAR" errors at startup

[jdubois]

I am using Spring Boot 1.0.0.RC2, and I didn't have this issue with 1.0.0.RC1.

I create an executable WAR with Spring Boot, and when I run it (java -jar myapp.war) I get the following errors. However, the application seems to be working fine.

[WARN] org.apache.tomcat.util.scan.StandardJarScanner - Failed to scan JAR [jndi:/localhost/WEB-INF/lib/spring-context-4.0.1.RELEASE.jar] from WEB-INF/lib
