I have a web application that uses Apache Common IO version 2.4. When I deploy this application on Tomcat 8.0.39 I am getting following error:
> [ERROR] - class "org.apache.commons.io.FilenameUtils"'s signer information does not match signer information of other classes in the same package
java.lang.SecurityException: class "org.apache.commons.io.FilenameUtils"'s signer information does not match signer information of other classes in the same package
