[jboss-jira] [JBoss JIRA] Closed: (JBCL-12) Add a cache of found resources by root to the VFSClassLoader

[Adrian Brock (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBCL-12?page=all ]

Adrian Brock closed JBCL-12.
----------------------------

    Resolution: Done

The VFSClassLoader now uses such a Soft Cache.
i.e. the cache (can and) will be cleared when memory is tight.

> When defining a class in the VFSClassLoader we use findChild() a number of times;
> 1) In the search of the classloaders to see whether the classloader has the class
> 2) To open the byte stream of the class
> 3) To determine the protection domain of the class (i.e. the root of class)
> 4) To locate the manifest to determine package information
> Some of this already has a cache in various places. But this could be further optimised
> by caching of resource path -> vfs file/root during the defineClass()
