Grails startup after adding lazy false to domain class taking forever on IntelliJ IDEA -

i facing org.hibernate.lazyinitializationexception: not initialize proxy - no session issue in this answer. used second option, i.e. making association between domain classes non lazy (lazy:false)

but when try run app, waiting 15mins. application not start!!!

i using grails 2.2.1 on intellij idea 12.1.4.

here bit of code(poolservice.groovy):

def removechildfrompool(accounttofollow accounttofollow){     try {         def pool=pool.first()         if(!pool.isattached()){             pool.attach()         }         if(!accounttofollow.isattached()){             accounttofollow.attach()         }         pool.removefromaccounttofollow(accounttofollow)         pool.save(flush:true)          accounttofollow.delete(flush: true)         return true     } catch (exception e) {         return false     } } 

attach above not work , gives false. modified domain class below(just added static constraints lazy:false):

class pool {     //can account id or name dependent on input csv format     string poolname     static hasmany = [accounttofollow:accounttofollow]     static constraints = {         poolname nullable: false,unique: true         accounttofollow nullable: true     } 

//added later on , changed caused grails not restart static mapping={ accounttofollow lazy: false } }
