grails - GRAILS 2.0异常:-java.lang.VerifyError:(class:xls/Recruitment，方法:initErrors signature:()V)无法将操作数从空堆栈中弹出

Question

我正在尝试运行grails应用程序，但出现以下异常

严重:异常将上下文初始化事件发送到类org.codehaus.groovy.grails.web.context.GrailsContextLoaderListener的侦听器实例

**org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grailsApplication' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.VerifyError: (class: xls/Recruitment, method: initErrors signature: ()V) Unable to pop operand off an empty stack**

我使用的是grails 2.0和Recruitment类，异常(exception)是域类。

package xls

class Recruitment implements Serializable {

    String id
    String position
    String candidateName
    String noticePeriod
    String hrAgencyName
    String cellPhone
    String profileSourcingData
    String totalWorkExperience
    String emailAddress
    String currentCTC
    String expectedCTC
    String currentPosition
    String currentOrganisationName
    String communication
    String bankingOrFinancialDomainKnowledge
    String clientManagementExperience
    String reasonForChange
    String firstInterviewBy
    String secondInterviewBy
    String interviewStatus
    String offerDate
    String expectedDateOfJoining
    String joiningTeamName

    static constraints = {
         position(blank:true, nullable:true)
         candidateName(blank:true, nullable:true)
         noticePeriod(blank:true, nullable:true)
         hrAgencyName(blank:true, nullable:true)
         cellPhone(blank:true, nullable:true)
         profileSourcingData(blank:true, nullable:true)
         emailAddress(blank:true, nullable:true)
         totalWorkExperience(blank:true, nullable:true)
         currentCTC(blank:true, nullable:true)
         expectedCTC(blank:true, nullable:true)
         currentPosition(blank:true, nullable:true)
         currentOrganisationName(blank:true, nullable:true)
         communication(blank:true, nullable:true)
         bankingOrFinancialDomainKnowledge(blank:true, nullable:true)
         clientManagementExperience(blank:true, nullable:true)
         reasonForChange(blank:true, nullable:true)
         firstInterviewBy(blank:true, nullable:true)
         secondInterviewBy(blank:true, nullable:true)
         interviewStatus(blank:true, nullable:true)
         offerDate(blank:true, nullable:true)
         expectedDateOfJoining(blank:true, nullable:true)
         joiningTeamName(blank:true, nullable:true)
    }


    static mapping = {
            id generator:'assigned'

     }


}

我在Grails 2.2.0应用程序中遇到了java.lang.VerifyError，这是因为GSP文件中的Groovy表达式被注释掉了，这显然使Grails缓存机制中断了。删除注释掉的表达式可解决此问题。
