Tomcat error "Unable to process Jar entry" for all javassist classes

[ryber]

Hello, I recently upgraded javassist in a project that was moving to Java 8. When tomcat starts we get errors for what looks like every class in javassist. I'm pretty sure it's just because tomcat is looking for servlets and such (which it's not going to find anyway) but it's concerning anyway. Here is the error:

@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

[yamass]

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

[DaiDongLiang]

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

[chibash]

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

Below exclusion fixed my problem. It might help you.

<dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>5.1.0.Final</version>
            <exclusions>
                <exclusion>

I have involved with it too,updating to tomcat-8.0.33 ,it solved.

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>

catalina.properties file:

tomcat.util.scan.DefaultJarScanner.jarsToSkip=javassist-*.jar
