Hi all, I want to use *jackson-module-scala_2.11:2.7.5* in my *Apache Flink* codebase. When I attempt to run the code I get
java.lang.VerifyError: Cannot inherit from final class > at java.lang.ClassLoader.defineClass1(Native Method) > at java.lang.ClassLoader.defineClass(ClassLoader.java:800) > at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) > at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) > at java.net.URLClassLoader.access$100(URLClassLoader.java:71) > at java.net.URLClassLoader$1.run(URLClassLoader.java:361) > at java.net.URLClassLoader$1.run(URLClassLoader.java:355) > at java.security.AccessController.doPrivileged(Native Method) > at java.net.URLClassLoader.findClass(URLClassLoader.java:354) > at java.lang.ClassLoader.loadClass(ClassLoader.java:425) > at java.lang.ClassLoader.loadClass(ClassLoader.java:358) > at > com.fasterxml.jackson.module.scala.modifiers.OptionTypeModifierModule$class.$init$(OptionTypeModifierModule.scala:22) > at > com.fasterxml.jackson.module.scala.DefaultScalaModule.<init>(DefaultScalaModule.scala:19) > at > com.fasterxml.jackson.module.scala.DefaultScalaModule$.<init>(DefaultScalaModule.scala:36) > at > com.fasterxml.jackson.module.scala.DefaultScalaModule$.<clinit>(DefaultScalaModule.scala) I looked up on the web and it appears to be a versioning issue. In my far jar I see that I have both *org.codehaus.jackson* and *com.fasterxml.jackson* packages. In particular, Flink's core library uses *jackson-core-asl:1.9.13* and *jackson-mapper-asl:1.9.13*, which I can't really change. Can anyone help me solve this issue?
