WW-4266 Adds support for IBM JVM to reload resources (lukaszlenart: rev 9c5177c961fb850b80089ef4113a17d361c23fa6)
* xwork-core/src/main/java/com/opensymphony/xwork2/util/LocalizedTextUtil.java
> resource reloading does not work in IBM JVM
> -------------------------------------------
>
> Key: WW-4266
> URL: https://issues.apache.org/jira/browse/WW-4266
> Project: Struts 2
> Issue Type: Bug
> Components: Core Actions
> Affects Versions: 2.3.16
> Environment: WAS 8.5 with IBM JVM 6
> Reporter: Christoph Nenning
> Assignee: Lukasz Lenart
> Priority: Trivial
> Fix For: 2.3.17
>
> Attachments: struts2-fix-resources-reloading-in-ibm-jvm.patch
>
>
> When resources reloading is enabled, LocalizedTextUtil uses reflection to clear a private
static map of the ResourceBundle class. The member name of that map is "cacheList".
> The IBM JVM has a different impl of ResourceBundle which does not have the "cacheList"
member. That causes a lot of NoSuchFieldExceptions in log and resource reloading does not
work.
> To fix it the patch catches NoSuchFieldException and uses clearMap() to clear the cache
of that IBM ResourceBundle (which is just called "cache").
> Notes:
> - Javadoc indicates that that IBM code is based on the Apache Harmony project
> - The type of that cache member is:
> WeakHashMap<ClassLoader, Hashtable<String, ResourceBundleSoftRef>>
> So one could argue that the patch clears too much, but IMHO that is OK as it is intended
for development mode anyway.
