Davanum Srinivas resolved AXIS-2232:

    Resolution: Fixed

Applied patch


> Mappings in TypeDesc can't be GC'ed
> -----------------------------------
>          Key: AXIS-2232
>          URL:
>      Project: Apache Axis
>         Type: Improvement
>   Components: Deployment / Registries
>     Versions: current (nightly)

> The TypeDesc class holds a static Hashtable of class -> TypeDesc mappings.  This is
fine if Axis is loaded into the only the same classloader as the app itself (like when it's
embedded in a webapp), but if axis is loaded into the parent classloader of all webapps, the
hashtable will prevent those children classloaders from being garbage collected as it holds
references to classes in those children classloaders.
> This patch 1) creates a Hashtable of class->TypeDesc for *each classloader* and 2)
stores those hashtables in a WeakHashMap so they can be garbage collected when the child classloaders
are garbage collected.
