Classloading Gotcha in JDK6

by Jason T. Greene

FYI, There is an undocumented system property (besides the jvm source) in JDK 5 and 6 called "sun.lang.ClassLoader.allowArraySyntax". The default changed from true to false in JDK6. So what this means is that in JDK6, unless you set that property to true, if you try and load a Java array type using a classloader (e.g. "[[B") you will get a CNFE. The compatible solution is to either interpret array types directly (not hard), or to use the extended form of Class.forName(), which does understand the array syntax: Class clazz = Class.forName(className, false, loader); http://jira.jboss.com/jira/browse/JBCOMMON-25 -- Jason T.
