Grails 2.5.0: Reloading of enums fails

[zaccak]

If I'm running a Grails application and I change an enum it wont reload it. I will have to shut down the app and run-app again to fix it.

Please fix.

I tried to reproduce this by creating an enum and rendering a enum value, then changing the enum and rendering the newly added value and I received no such exception, if you want any progress on this issue you will need to upload an example to github with steps to reproduce

Hi Graeme,

I'm able to reproduce it using the following:
0. Make a new project: EnumBreaker

1. Make an emum:
   package enumbreaker.enums
   enum ProvinceEnum {
   AB("Alberta"),
   BC("British Columbia"),
   MB("Manitoba"),
   NB("New Brunswick"),
   NF("Newfoundland and Labrador"),
   NT("Northwest Territories"),
   NS("Nova Scotia"),
   NU("Nunavut"),
   ON("Ontario"),
   PE("Prince Edward Island"),
   QC("Quebec"),
   SK("Saskatchewan"),
   YT("Yukon")

   private final String value

   ProvinceEnum(String value) {
   this.value = value
   }

   String toString() {
   return value
   }
   }

2. Make a domain that uses that enum:
   package enumbreaker
   import enumbreaker.enums.ProvinceEnum
   class Clinic {

   String name
   ProvinceEnum province

   static constraints = {

   }
   }

3. Run-app

4. Now change the enum (remove the last YT or add something new)

5. You should get this:

I followed your steps and I cannot reproduce with the master branch, maybe it has already been fixed by another commit

I can give it another shot when 2.5.1 comes out.

I should note that I'm running Grails 2.5.0 on Mac OS X 10.10.3 and Groovy/Grails Tool Suite Version: 3.6.4.RELEASE.
