lang.IllegalAccessError: tried to access method

運行得好好的程序，在pom.xml加入了一些其它jar包依賴後，忽然沒法啓動（啓動方式是建立一個Spring Application Context）：

Exception in thread "main" java.lang.IllegalAccessError: tried to access method 
org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingletonMutex()Ljava/lang/Object;

網上相似錯誤還有：（轉自http://www.cnblogs.com/coveted/archive/2012/03/06/2381757.html）

    緣由是spring-data-jpa.jar的版本和spring-data-commons-core.jar的版本不匹配所形成的,spring-data-commons-core.jar的版本太高了.
在發生異常的時候個人版本是:spring-data-jpa-1.0.2.RELEASE.jar和spring-data-commons-core-1.3.0.M1.jar
更改後:spring-data-jpa-1.0.2.RELEASE.jar和spring-data-commons-core-1.1.0.RELEASE.jar (OK)

還有：java.lang.AbstractMethodError: org.springframework.data.jpa.repository.config.SimpleJpaRepositoryConfiguration.getRepositoryBaseInterface()Ljava/lang/Class;

緣由：加入的spring-data-jedis包中引入了另一個版本的spring-core，與現有衝突。

解決：在pom中exclude新版本的spring-core。
