You're trying to load a class (SecurityNamespaceHandler) that was compiled with a newer version of Java than the version of Java that you are using.

Major version 52 indicates that this class requires Java 8.

More info here: How to fix java.lang.UnsupportedClassVersionError: Unsupported major.minor version
