Description

It took me a very long time to narrow down to this bug because stacktrace contains useless logs.

Very easy to reproduce.
1- Create a project
2- Create a domain class
3- Add method :
def getName(int i)

{ return "uehfi" }

4- grails run-app => BOUM when starting the application

If you replace the method by def getName(Integer i), then it works ??!!!

Project attached.

Did you run the project on Windows?? I tried on 2 different machines (Windows Vista and Windows 7) and I always get a NPE at startup with:

ERROR context.GrailsContextLoader - Error executing bootstraps: Error creating bean with name 'pluginManager' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

Please see my comments. I have given the attached project to another person that has also experienced the startup failure

No I tried it on Mac OS X.

Reducing priority since it only effects a small subset of environments. It would help if you attached your stacktrace.log file.

I have no idea how this exception could possibly occur because the getType() method cannot return null, anyway I've added a null check which should fix the problem, however I cannot reproduce (not even on a local Windows VM) so cannot be sure:

Very strange that you cannot reproduce it. If currentProp.getType() returns null, I believe that other issues will be raised. I will test 1.3.3 and post my results on this Jira issue.
