Description

Since I have upgraded to 1.3.1, it seems while running my grails application in development mode, I cannot modify anymore some of my services during runtime.
If I do change the service file, I got the following error :

Caused by: java.lang.ClassCastException: com.irofoot.VoteService cannot be cast to com.irofoot.VoteService
at com.irofoot.VoteService$$FastClassByCGLIB$$e974f44.invoke(<generated>
at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149)
at com.irofoot.VoteService$$EnhancerByCGLIB$$21cefb3d.getMetaClass(<generated>
at com.irofoot.VisualizationService.getGoogleChartUrl(VisualizationService.groovy:19)
at GrailsMelodyGrailsPlugin$_closure5_closure18_closure19.doCall(GrailsMelodyGrailsPlugin.groovy:136)
at com.irofoot.VizuTagLib$_closure3.doCall(VizuTagLib.groovy:21)
... 10 more

This is quite annoying because I need to restart the application in dvt mode each time I need to change a Service class!!

It might be related to the annotation @Transactional. I need to test it but it seems that this exception occurs when a service has a method having the @Transactional annotation defined. Other services without this annotation seems to work just fine

Please attach a project with a service class that exhibits this behaviour on reload.

Project attached. Just run "grails run-app", then go to the unique controller to see that it is working fine. Then go to the unique service, change something in OneService code, save, refresh browser => BOOM ! (com.try6.OneService cannot be cast to com.try6.OneService)

I am also having this issue, including in inline plugins I work with (seeing the issue as late as 1.3.4 and 1.3.5). I do not use @Transactional.

If anybody has any ideas as to what it might be, let me know - I can gave some guys on my team spend some time looking at it, but not sure where to start.

I have re-opened https://jira.springsource.org/browse/SPR-4153 as it is the root cause. I have also proposed a workaround in Grails until the Spring issue is fixed. If approved, this will be fixed in 1.3.6.

Note: the ?aop-reloading-fix? plugin can be installed in earlier versions of Grails to fix this issue.

I've just tried the plugin on grails 1.3.1, and was getting the following:

 
Plugin aop-reloading-fix-0.1 requires version [* < 1.3.5] of Grails which your current Grails installation does not meet. Please try install a different version of the plugin or Grails.

I hacked the Ivy zip to use use the following: 1.2-M3 > * and it seemed to install ok. The grails version currently defined is: 

def grailsVersion = "* > 1.3.5"

which I guess is incorrect?

The plugin is not working for Spring Security ACL annotations. Any ideas? Thank you!
