Iterating through a list in another list in groovy

I need to iterate over users list in groups list and if users list has the group(from group list) I need remove that from users list. I tried the following but its not working

def groupsList = entity.companyContainer.groups
groupsList.each { g ->
    g.users.each { u ->
       if( u.groups.find( g ) ) {
           u.groups.remove( g )
           entityService.update( u )  
       }
    }
    entityService.delete(g)
}

Exception:

ERROR | com.core.common.controller.impl.BaseMultiActionController | groovy.lang.MissingMethodException:
No signature of method: 
    com.core.configuration.persistence.ListWithPersistentSetPropertyAccessor$ListWit‌​hPersistentSet.find()
    is applicable for argument types: (com.core.security.model.impl.Group) values: [LFO Super Users_Lawfirm]
 Possible solutions: find(groovy.lang.Closure),
                     find(groovy.lang.Closure),
                     min(),
                     min(groovy.lang.Closure),
                     min(java.util.Comparator),
                     size()

Although I am not clear about the full context of the logic but you can get what you need using find{} as a closure operation as below:

def groupsList = entity.companyContainer.groups

groupsList.each{ g ->
   g.users.each {u ->
     if(u.groups.find{it.id == g.id}) {
        u.groups.remove(g)
        entityService.update(u)
     }
   }
   entityService.delete(g)
}
