I am having trouble getting TreeCacheAop to add objects of a class which extends ArrayList. According to the FAQ this is possible:
anonymous wrote : TreeCacheAop supports classes extending from List, Set, and Map without users to declare them "aspectized". It is done via a dynamic proxy. Simple objects such as Strings are being added and replicated with no errors, so the TreeCacheAop appears to be configured correctly. The class in question extends ArrayList. In my test code I create a new object of this class and try to add it to a TreeCacheAop using putObject(). At this point JBossCache bombs and throws an CacheException. This happens using three separate scenarios with jboss-aop.xml: 1) no jboss-aop.xml at all, 2) using a jboss-aop.xml with an "advisable" entry for my class as specified in the example jboss-aop.xml from the jboss-cache distribution, and 3) using a jboss-aop.xml with a "prepare" entry for my class as described in the TreeCacheAop document. So it appears that the jboss-aop.xml file is having no effect on this behavior, or at least the error is the same for the three configurations I've tried. Here is the exception stack trace: | 11:15:53,681 ERROR [TreeCacheTester] Unable to add a new UserMessages object for user ID JADAMS1 | org.jboss.cache.CacheException: failure creating proxy; - nested
