[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-3851) Seam reflection has lower access than Java reflection

Seam reflection has lower access than Java reflection ----------------------------------------------------- Key: JBSEAM-3851 URL: https://jira.jboss.org/jira/browse/JBSEAM-3851 Project: Seam Issue Type: Bug Affects Versions: 2.0.2.SP1 Environment: Jboss Embedded, Java 5 Reporter: Gabriel Goïc Assignee: Norman Richards Fix For: 2.1.2.CR1 This simple class is to be unit-tested, the SeamTest way: @Name("hibean") public class HiSayerBean { public HiSayerBean () { } protected void sayHi(){ System.out.println("hello"); } } All tests occur in the SeamTest framework: new ComponentTest() { @Override protected void testComponents() throws Exception { //test code } }.run(); Using Java Reflection - works: HiSayerBean impl = new HiSayerBean(); Method m = impl.getClass().getDeclaredMethod("sayHi"); m.setAccessible(true); m.invoke(impl); Using Java Reflection with Seam - fails: HiSayerBean impl = (HiSayerBean) getInstance("hibean"); Method m = impl.getClass().getDeclaredMethod("sayHi"); m.setAccessible(true); m.invoke(impl); Error log: java.lang.reflect.InvocationTargetException (...) Caused by: java.lang.IllegalAccessException: Class org.jboss.seam.util.Reflections can not access a member of class HiSayerBean with modifiers "protected" at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65) at java.lang.reflect.Method.invoke(Method.java:578) at org.jboss.seam.util.Reflections.invoke(Reflections.java:21) at org.jboss.seam.intercept.RootInvocationContext.proceed(RootInvocationContext.java:31) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:56) at org.jboss.seam.transaction.RollbackInterceptor.aroundInvoke(RollbackInterceptor.java:31) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.core.BijectionInterceptor.aroundInvoke(BijectionInterceptor.java:46) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.core.MethodContextInterceptor.aroundInvoke(MethodContextInterceptor.java:42) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68) at org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:107) at org.jboss.seam.intercept.JavaBeanInterceptor.interceptInvocation(JavaBeanInterceptor.java:166) at org.jboss.seam.intercept.JavaBeanInterceptor.invoke(JavaBeanInterceptor.java:102) at HiSayerBean_$$_javassist_0.sayHi(HiSayerBean_$$_javassist_0.java) ... 29 more So, using Seam gives me a lower capacity to access methods in a reflected class than with raw Java. I'm not sure if it's a bug or a feature request though. But it would be nice to be granted to do this in unit-testing. Please note that access to a private method in the same way than above works with Java but produces a java.lang.NoSuchMethodException with Seam.
