[jboss-jira] [JBoss JIRA] (WFLY-2493) EL cannot access public methods/fields of non-public classes

EL cannot access public methods/fields of non-public classes ------------------------------------------------------------ Key: WFLY-2493 URL: https://issues.jboss.org/browse/WFLY-2493 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: JSF Environment: JBoss AS 7.2.0.Final Reporter: Jonáš Trantina Attachments: elresolver_stack, reproducer.zip When trying to access public method/field of non-public class that implements public interface via EL I get {noformat} java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class X with modifiers "private" {noformat} E.g. accessing Collections.unmodifiableList(..).size() via EL will throw the exception, because #unmodifiableList returns non-public implementation of List interface. This is apparently caused by JDK-4071957 [1], but since that is opened for over 16 years, it should be probably worth it to implement a workaround. Workaround for this issue is setting setAccessible(true) on the method before invoking it, thus suppress Java access checking. I have attached a simple reproducer app as well as a stack trace of the exception. [1] http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4071957
