            Description

            1. Compat Showcase
            - Rich text: Error message displays on the page - Could not find resource at /component-showcase/icefaces/resource//LTQ5MTYyMDg1Mw==/editor/fckeditor.html
            - Menu bar: no sub menu is displayed
            - Split pane panel: divider is not draggable

            2. NullPointerException was seen a couple of times when testing compat showcase and compat auction, but could not reproduce when reran.

              • Menu bar: the sub menu does not display
              • Split pane panel: the divider is not draggable

              Those two failures in compat showcase are current glimmer regressions. Only Rich Text seems specific to Tomcat 7.

              RichText problem is also reproducible with Tomcat 6. It appears to be a transient problem, may require clearing the browser cache to reproduce.

              This bug is not yet fixed, but the component-showcase application should now work reliably. The WeakHashMap in DynamicResourceDispatcher.java has been replaced with a HashMap. Unfortunately, this results in the accumulation of some dynamically registered resources (such as with the chart demo).

              The reason that the WeakHashMap is not effective here is because the WeakHashMap uses weakly held keys. When the key can be garbage collected, then the WeakHashMap breaks the reference to the value. This essentially introduces random behavior into resource garbage collection because the lifetime of the key (often a dynamically generated path) is not strongly associated with the lifetime of the resource being served.

              See ICE-5787 for additional discussion on resource dispatching.

              Please verify that the RichText problems are now fixed in the trunk.
              This bug can be closed if the reported problems are not Tomcat 7 specific.
