------------------------------------------

I am seeing a similar issue except duplicates in the list after sorting.

When I sort a list returned from getFooList() using Collections.sort I am getting a \
duplicate in the list and teh collection size does not change.

If I try to sort list "aPLugin", "bPlugin", "cPLugin"

List<Plugin> pluginsList = xmlPlugins.getPluginList());
Collections.sort(pluginsList , new Comparator<Plugin>() {
                   public int compare(Plugin o1, Plugin o2) {
                           return o1.getName().compareTo(o2.getName());
                   }});


I get back plugins "aPLugin", "bPlugin", "aPLugin".

Plugins.getPluginList() (actually PluginsImpl.getPluginList()) returns a PluginList, \
which extends AbstractList<com.bea.usagetrack.protocol.v100.Plugin>. PluginList's \
get() and set() methods do some twisty stuff that looks like it should work for \
sort(), but obviously doesn't. Looks like some indirection in PluginsImpl is biting \
us for the sort().

If I create a new ArrayList first then it works

List<Plugin> newList = new ArrayList<Plugin>(xmlPlugins.getPluginList());
Collections.sort(newList, new Comparator<Plugin>() {
                      public int compare(Plugin o1, Plugin o2) {
                                 return o1.getName().compareTo(o2.getName());
                      }});

> I am trying to sort the list returned by the generated getFooList() [multiple \
> occurrence method] using java.util.Collections#sort(java.util.List<Type>, \
> java.util.Comparator<Type>). The elements are not sorted, and no exception is \
> thrown. I would expect either, but I do not see any reason for the list to be \
> unmodifiable (and thus throwing exception when trying to sort it). A simple \
> workaround is to create a new list supplying the original list (from the generated \
> method) in the constructor. The new list is sortable without any problems.
