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.
