java.lang.VerifyError: Inconsistent stackmap frames at branch target 81

　　java项目中有如下代码：

　　　　 @RequestMapping(value = "/getMxList")
　　　　 @ResponseBody
	public Map<String, Object> getMxList(HttpServletRequest req, Model model) throws ManagerException {
		String reportType = CommonUtil.getStrValue(req.getParameter("reportType"), "");
		try (CacheContext context = new CacheContext()) {
			if (reportType.equals("shop")) {
				return shopItemInvoicingReport(req, model, context);
			} else {
				return ItemInvoicingReport(req, model, context);
			}
		} catch (ManagerException e) {
			throw e;
		} catch (Exception e) {
			throw new ManagerException(e);
		} finally {
			String ticket = StringUtils.isEmpty(req.getParameter("tiket")) ? "" : String.valueOf(req
					.getParameter("tiket"));
			if (!StringUtils.isNotEmpty(ticket))
				req.getSession().removeAttribute(ticket);
		}

	}

　　

　　在eclipse中启动项目之后包如下错误：

　　解决方法：

　　　　加上VM options :  -XX:-UseSplitVerifier

　　　　

　　原因分析：

　　　　报异常的方法内使用了Java 7的新特性：自动资源释放，类似于try(){}，即在try后面跟一括号，在括号里面对一些资源赋值，try里面的代码块执行完毕之后会自动释放try后面的括号中声明的资源。

　　Java 7 会使用新的Class类型校验器，新的类型校验器将老的校验器分为两步：

　　　　　　1、类型推断

　　　　　　2、类型校验

　　　　新的类型校验器通过在javac编译时嵌入类型信息到bytecode中，省略了类型推断这一步，从而提升了classloader的性能。　　

　　Classload顺序(供参考)

　　load -> verify -> prepare -> resove -> init

　　

　　-XX:+UseSplitVerifier

　　Enables splitting of the verification process. By default, this option was enabled in the previous releases, and verification was split into two phases: type referencing (performed by the compiler) and type checking (performed by the JVM runtime). This option was deprecated in JDK 8, and verification is now split by default without a way to disable it.

　　　　As of Java 7, compiled bytecode has to contain additional StackMapTable attributes. These help the verifier inside the JVM to check that classes are soundly constructed, at class loading time. Earlier versions of Java are more lenient, falling back on the slower verification without attributes.

Tools that modify the original compiled bytecode (ProGuard right after the compilation, AOP frameworks right before the execution,...) need to update the attributes consistently with the modified code. If they fail to do so, you'll get the error message "Inconsistent stackmap frames".

ProGuard should perform this preverification fine; I'm not aware of any problems with it. If you still see the error without applying ProGuard, the problem must lie with the DI or AOP.
