Auto deployment failure on CentOS 7 tomcat with unpackWAR="false" in 3.4.0 update

[Takeshi NISHIMURA]

Hi all,

We have encountered a strange error when updating Shibboleth IdP to 3.4.0 on CentOS 7-supplied tomcat package (Tomcat 7).

It is auto-deployment failure and it works fine again when you manually restart Tomcat.

We also found that this error occurs only when unpackWAR="false". If you configure unpackWAR="true" or you do not specify it, you can use auto-deployment without such trouble.

Error message:
> SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
