I am getting the javassist exception while deployment the .EAR file . I am using Java 1.8 SDK , IBM JDK 1.8 . In my pom.xml file , i am using 3.19.0-GA javassit dependency and spring version 4.2.5.RELEASE . The error is getting
error

After analyzing the class file of javassit , i can see InvocationTargetException causing error
javassit jar file class code :
public Class toClass(CtClass ct, ClassLoader loader, ProtectionDomain domain)
/* */ throws CannotCompileException
/* */ {
/* */ try
/* */ {
/* 1065 */ byte[] b = ct.toBytecode();
/* */ Object[] args;
/* */ Method method;
/* 1068 */ Object[] args; if (domain == null) {
/* 1069 */ Method method = defineClass1;
/* 1070 */ args = new Object[] { ct.getName(), b, new Integer(0), new Integer(b.length) };
/* */ }
/* */ else
/* */ {
/* 1074 */ method = defineClass2;
/* 1075 */ args = new Object[] { ct.getName(), b, new Integer(0), new Integer(b.length), domain };
/* */ }
/* */
/* */
/* 1079 */ return toClass2(method, loader, args);
/* */ }
/* */ catch (RuntimeException e) {
/* 1082 */ throw e;
/* */ }
/* */ catch (InvocationTargetException e) {
/* 1085 */ throw new CannotCompileException(e.getTargetException());
/* */ }
/* */ catch (Exception e) {
/* 1088 */ throw new CannotCompileException(e);
/* */ }
/* */ }
code :
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.springframework.aop.framework.ProxyCreatorSupport");
CtConstructor c = cc.getConstructors()[0];
c.insertAfter("$0.aopProxyFactory = new org.springframework.aop.framework.JavassistAopProxyFactory();");
cc.toClass();
} catch (Exception e) {
throw new IllegalStateException(e);
}
}
}
This code was working fine with JDK 1.6 and javassit 3.12 . Any suggestion ?
