I am using spring

<properties>
        <spring.version>4.2.5.RELEASE</spring.version>
        <spring-ws.version>2.4.0.RELEASE</spring-ws.version>
        <spring-security.version>4.0.0.RELEASE</spring-security.version>
        <slf4jVersion>1.6.1</slf4jVersion>
        <maven.test.skip>true</maven.test.skip>
        <junit.version>4.8.2</junit.version>
        <hibernate.version>3.5.6-Final</hibernate.version>
   </properties>

and javassit

<!-- Javassist -->
        <dependency>
            <groupId>javassist</groupId>
            <artifactId>javassist</artifactId>
            <version>3.19.0-GA</version>
        </dependency>

But when i deploy same application on JDK 1.6 , it was working fine with out any exception error .

I am getting errors on

package org.spring.aop.framework;

import javassist.ClassPool;
import javassist.CtClass;
import javassist.CtConstructor;
import javassist.LoaderClassPath;
import org.springframework.web.context.support.XmlWebApplicationContext;

public class JavassistApplicationContext extends XmlWebApplicationContext {

    static {
        ClassPool classPool = ClassPool.getDefault();
        try {
            ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
            classPool.appendClassPath(new LoaderClassPath(classLoader));

            CtClass cc = classPool.get("org.spring.aop.framework.ProxyCreatorSupport");
            CtConstructor c = cc.getConstructors()[0];
            c.insertAfter("$0.aopProxyFactory = new org.spring.aop.framework.JavassistAopProxyFactory();");
            cc.toClass();
        } catch (Exception e) {
            throw new IllegalStateException(e);
        }
    }
}

Any idea ? Anything i am missing ?

Please note that we do not support Javassist proxies in the Spring AOP framework. Such custom Javassist setup classes are effectively part of your project, even if they got derived from somebody's Spring support classes. Since they are not an official part of Spring, we cannot provide any support for them and cannot spend any time debugging them either.
