Getting error while running Webservices on Tomcat7 server - Ubuntu 16.04 LTS - tomcat7

Question

Technical Environment:-
Ubuntu 16.04 LTS
Tomcat 7
Java 7
Eclipse Luna
I have imported a webservice into my eclipse luna workspace and tried to run that service on tomcat7 server. But I'm getting the following error.

Please point me out to the possible solution. Thank you so much.

I had the same problem recently.
It seems that Tomcat 7 classes were compiled using Java 8 libraries in Ubuntu 16.04, so you cannot run it using Java 7.
This is from catalina.jar (7.0.68) from repository:
# javap -verbose org/apache/catalina/core/ApplicationContext.class
Classfile /usr/share/tomcat7/lib/org/apache/catalina/core/ApplicationContext.class
Last modified 27/06/2016; size 33798 bytes
MD5 checksum b176f6c6f5854428fbfa67b298ed308a
Compiled from "ApplicationContext.java"
public class org.apache.catalina.core.ApplicationContext implements javax.servlet.ServletContext
SourceFile: "ApplicationContext.java"
InnerClasses:
public static #479= #478 of #943; //Dynamic=class javax/servlet/FilterRegistration$Dynamic of class javax/servlet/FilterRegistration
public static #479= #511 of #945; //Dynamic=class javax/servlet/ServletRegistration$Dynamic of class javax/servlet/ServletRegistration
public static #1005= #1004 of #2; //KeySetView=class java/util/concurrent/ConcurrentHashMap$KeySetView of class java/util/concurrent/ConcurrentHashMap
minor version: 0
major version: 50
flags: ACC_PUBLIC, ACC_SUPER
And this is from catalina.jar (7.0.68) downloaded from Apache:
# javap -verbose org/apache/catalina/core/ApplicationContext.class
Classfile /root/apache-tomcat-7.0.68/lib/org/apache/catalina/core/ApplicationContext.class

Compiled from "ApplicationContext.java"
public class org.apache.catalina.core.ApplicationContext implements javax.servlet.ServletContext
SourceFile: "ApplicationContext.java"
InnerClasses:

public static #481= #513 of #948; //Dynamic=class javax/servlet/ServletRegistration$Dynamic of class javax/servlet/ServletRegistration
minor version: 0
major version: 50
flags: ACC_PUBLIC, ACC_SUPER
Both are compiled to class format 50 (Java 6), but the repository class has a link to a Java 8 exclusive method:
public static #1005= #1004 of #2; //KeySetView=class java/util/concurrent/ConcurrentHashMap$KeySetView of class java/util/concurrent/ConcurrentHashMap
So if you want to run Tomcat 7 with Java 7 in Ubuntu 16.04 you have to download it directly from Apache and install it manually.
