[jira] Updated: (BEANUTILS-59) [beanutils] Memory leak on webapp undeploy in WrapDynaClass
[ https://issues.apache.org/jira/browse/BEANUTILS-59?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Niall Pemberton updated BEANUTILS-59: - Attachment: beanutils-59.patch Theres 2 problems here: 1) The memory issues itself 2) The fact that the HashMap is exposed as as a protected instance which means removing it or changing the implementation breaks binary compatibility To resolve the memory issue I propose we put the cache(i.e. Map) inside a static ContextClassLoaderLocal instance - that way there will be one Map per ClassLoader in a WeakHashMap. To resolve the binary compatibility I propose we create a HashMap implementation with all its methods overriden to delegate to the Map instances in the ContextClassLoaderLocal.
