Cloning org.jboss.invocation.InterceptorContext leaks memory ------------------------------------------------------------ Key: WFLY-4187 URL: https://issues.jboss.org/browse/WFLY-4187 Project: WildFly Issue Type: Bug Affects Versions: 8.1.0.Final, 8.2.0.Final Reporter: Jeroen Wielandt Assignee: Eduardo Martins Fix For: 9.0.0.CR1 The clone function uses sublist to set the new list of interceptors. public InterceptorContext clone() { .... clone.setInterceptors(interceptors.subList(next, interceptors.size())); return clone; } This will keep a reference to the original list around. So the original list will never be released. Chaining clone multiple times will eventually cause an out of memory because each sublist grows slightly.
