如何看到由Spring隐藏的嵌套异常跟踪？

Question

Error creating bean with name '...' defined in file [...Tester.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property '...' threw exception; nested exception is java.lang.IllegalArgumentException: ...

下面是完整的输出。可以看到IllegalArgumentException发生的地方可能被截断了。

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mybean' defined in file [D:\mypath\myconfig.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:

由于可能存在多个异常，您需要捕获PropertyBatchUpdateException并调用GetPropertyAccessExceptions()来检查特定异常的堆栈跟踪。

实际上我不太清楚这是怎么回事

public void printStackTrace(PrintWriter pw) {
        synchronized (pw) {
            pw.println(getClass().getName() + "; nested PropertyAccessException details (" +
                    getExceptionCount() + ") are:");
            for (int i = 0; i < this.propertyAccessExceptions.length; i++) {
                pw.println("PropertyAccessException " + (i + 1) + ":");
                this.propertyAccessExceptions[i].printStackTrace(pw);
            }
        }
    }
