Component class obfuscates IllegalArgumentExceptions from Reflections class
---------------------------------------------------------------------------

                 Key: JBSEAM-1080
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1080
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.2.0.GA
         Environment: Seam 1.2.0PATCH1, OS X 10.4.9, JDK 1.5, JBOSS 4.0.2
            Reporter: Stuart Robertson
            Priority: Minor


Reflections.java:63 generates a very clear exception message when rethrowing IllegalArgumentException.  In stepping through the debugger for instance, here's what I saw was the message at this point:

Could not set field value by reflection: CatalogItemSearchAction.itemFilterCriteriaSelection on: com.fb.core.action.CatalogItemSearchAction with value: class com.fb.util.criteria.ItemFilterCriterion

Outstanding.  

However this exception is then caught by Component.java:1559 by the following method:

   private void setFieldValue(Object bean, Field field, String name, Object value)
   {
      try
      {
         Reflections.set(field, bean, value);
      }
      catch (Exception e)
      {
         throw new IllegalArgumentException("could not set field value: " + getAttributeMessage(name), e);
      }
   }

...and the beautiful message is lost.  Below is the complete stacktrace seen in the application.
