[jbosstools-issues] [JBoss JIRA] (JBIDE-17866) JSF/KB memory leak

[ https://issues.jboss.org/browse/JBIDE-17866?page=com.atlassian.jira.plugi... ] Viacheslav Kabanovich edited comment on JBIDE-17866 at 7/18/14 6:10 PM: ------------------------------------------------------------------------ Partial fix for 4.2.0 is suggested: 1. UniquePaths is cleaned. 2. KbProjectFactory.mockProjectStore is cleaned - that is enough to throw KbProject objects to the garbage collector. 3. Listeners added by XModel objects to resource model and Java model are removed. At this time it is not easy to find all places that can hold XModel objects (FileSystemsImpl, FolderImpl, etc.). The best way to approach the problem is to implement destroy() method that completely disassembles model structure and call it at project deletion. For sure, doing it now is unsafe because it will result in a lot of exceptions so that I suggest implementing it in the next version. XModelMetaDataImpl object is a singleton that should not be released - it contains metadata which is used not only for projects but also for wizards and preferences. There is no way to separate safely part of metadata that can be released. was (Author: scabanovich): Partial fix for 4.2.0 is suggested: 1. UniquePaths is cleaned. 2.
