[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1190) ModuleProperties could cause memory leaks

    [ https://issues.jboss.org/browse/ISPN-1190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12609221#comment-12609221 ] 

Galder Zamarreño commented on ISPN-1190:
----------------------------------------

True, most likely it'd be used by other Infinispan modules, but nothing really stops ends users from defining their own commands. So, the option is always there to cause some havoc.

> ModuleProperties can create class memory leaks, because it contains static collections with references to user defined classes:
> {code}private static Map<Byte,Class<? extends ModuleCommandInitializer>> commandInitializers;
> private static Collection<Class<? extends ReplicableCommand>> moduleCommands;{code}
> Also, the following two collections could contain references to instances of user defined classes in static collections:
> {code}private static Map<String,ModuleProperties> moduleProperties;
> private static Map<Byte,ModuleCommandFactory> commandFactories;{code}
> These collections should not be static, and their clearing should be guaranteed at stoppage time. Even if there's any issues at stoppage time, they should not leak and so any collections containing Class instances should be weakly referenced.
