[jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - MethodInvocation.getArguments return value for 0 arguments

[sergeypk]

Hi,

I'm trying to debug this problem: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=104450&postdays=0&postorder=asc&start=10.

The exception is thrown from this aspect:
   public Object handleCreateTextMessage(Invocation invocation) throws Throwable
  |    {  
  |       JBossTextMessage jbm = new JBossTextMessage(0);
  |       
  |       MethodInvocation mi = (MethodInvocation)invocation;
  |       
  |       if (mi.getArguments() != null)
  |       {
  |          jbm.setText((String)mi.getArguments()[0]);
  |       }
  |       
  |       return new TextMessageProxy(jbm);
  |    }   
  | 

What should MethodInvocation.getArguments() return when there are no arguments? Can it ever return null? Do all AOP versions behave the same way or has this changed?

Thanks,
Sergey
