Inconsistent stack height 2 != 1

[Ankit Chandrawat]

Hi,

I am getting this error while I am restarting my server. I am using Jboss and Java 1.5 with Spring and hibernate 3.0. The OS is unix.

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mercer.chat.app.dao.ChatSessionDAO com.mercer.chat.app.businessmodel.ChatSessionBO.chatSessionDAO; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'chatSessionDAO' defined in file [/local/jboss-eap-4.2/jboss-as/server/mercer02/deploy/mercerhr.ear/mercer.war/WEB-INF/classes/com/mercer/chat/app/dao/ChatSessionDAO.class]: Initialization of bean failed; nested exception is java.lang.VerifyError: (class: com/mercer/chat/app/dao/ChatSessionDAO$$EnhancerByCGLIB$$c4629570$$FastClassByCGLIB$$d809ed40, method: invoke signature: (ILjava/lang/Object;[Ljava/lang/Object;)Ljava/lang/Object;) Inconsistent stack height 2 != 1

Here is my ChatSessionDAO.java

Updates: I just found out that the eror is coming due to this :

Is there any way around to solve this issue ?
