【问题描述】：
您好，我使用 EclipseEE 和 Java8_40。我从 Spring Framework 开始，遇到了一些问题。当我想在 beans.xml 中使用构造函数时，程序会创建一个异常。
我在 CLASSPATH 中：
- commons-logging-1.2.jar
- commons-logging-1.2-javadoc.jar
和 Spring *.jars
- spring-aop-4.1.5.RELEASE.jar
- spring-asm-3.1.1.RELEASE.jar
- spring-beans-4.1.5.RELEASE.jar
- spring-context-4.1.5.RELEASE.jar
- spring-aspects-4.1.5.RELEASE.jar
- spring-context-support-4.1.5.RELEASE.jar
- spring-core-4.1.5.RELEASE.jar
- spring-web-4.1.5.RELEASE.jar
- spring-webmvc-4.1.5.RELEASE.jar
- spring-expression-4.1.5.RELEASE.jar

public void setInitial(int initial) {
this.initial = initial; }
public synchronized String getSequence() {
StringBuffer buffer = new StringBuffer();
buffer.append(prefix);
buffer.append(initial + counter++);
buffer.append(suffix);
return buffer.toString(); }
