@ryber Have you been able to solve the problem? I am facing the same...

[ryber]

We excluded the Jar from Tomcat's scanning: https://tomcat.apache.org/tomcat-8.0-doc/config/jar-scan-filter.html

@ryber I solved my problem by updating to apache-tomcat-7.0.59

I have encountered the same problem in tomcat 8.0.9.
How to solve this problem?

Can't you fix the problem by substituting javassist-3.20.0-GA.jar for 3.19.0?

[finansistpavel]

You can add tomcat.util.scan.StandardJarScanFilter.jarsToSkip= ...,javassist-*.jar to catalina.properties file in your tomcat conf folder

Any of previous replies solved my situation. Using Hibernate, is mandatory to include a javassist jar Deploying my app into an openshift server, i was getting the same error and could solve it magically, adding explicitly the redhat maven's javassist dependency below:
<dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.18.1.GA-redhat-1</version> </dependency>
