cas入门之三十二： jpa ticketregistry在实际应用的一个bug

项目所应用的cas 3.5.2，运行环境为tomcat7.0.52.
因项目需要，所以将cas　ticket经jpa持久化到oracle　11g 数据库。根据这个cas 3.5.2的pom.xml文件，所应用的hibernate jar罗列如下：
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.1.0.Final.jar
hibernate-entitymanager-4.1.0.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-validator-4.2.0.Final.jar
相应的ticketRegistry.xml文件内容：
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
       http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">
   
        Configuration for the default TicketRegistry which stores the tickets in-memory and cleans them out as specified intervals.
          
    
   
        
    
        
        
            
                
                
            
        
        
            
                 ${database.hibernate.dialect}
                ${database.hibernate.hbm2ddl.auto}
            
        
    
    
                                          p:entityManagerFactory-ref="jpaEntityManagerFactory" />
    
    
             class="org.jasig.cas.ticket.registry.support.JpaLockingStrategy"
        p:uniqueId="${host.name}" p:applicationId="cas-ticket-registry-cleaner" />
        
    
    
             class="org.jasig.cas.ticket.registry.support.DefaultTicketRegistryCleaner"
        p:ticketRegistry-ref="ticketRegistry" p:lock-ref="jpaCleanerLock" p:logUserOutOfServices="true"/>
             class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"
        p:targetObject-ref="ticketRegistryCleaner" p:targetMethod="clean" />

             p:jobDetail-ref="jobDetailTicketRegistryCleaner" p:startDelay="20000"
        p:repeatInterval="1200000" />


cas应用运行一段时间，就会报如下错误：

最初没有在意,在渡娘上渡了一下没有找到相应的解决方案。但是这个错误频频出现，只好花一个上午存细研究了一下这个错误文件。
我发现它是因为hibernate的乐观锁造成的错误，怀疑是hiberate 4与cas3.5.2兼容不是很好，具体就是hibernate4与cas中应用的jpa兼容不是很好，
因为它报出的错误是hibernate3的错误（因为我对hibernate了解不多）。
于是决定换jar包：
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.1.0.Final.jar
hibernate-entitymanager-4.1.0.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-validator-4.2.0.Final.jar
换成
hibernate3.jar(3.6.10版本)
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-validator-4.2.0.Final.jar
其他不变，重启tomcat服务器，现在运行了几天了一切正常，没有报任何错误。
