Memory leak related to introspection information when executing a lot of Velocity scripts with the same context

The Velocity context contains a cache of introspection related information (like the methods).

It's not really clear to me what is the point of this cache since the following script will create 2 entries in this cache:

$var.foo()
$var.foo()

Anyway the problem is that this cache can quite big and more importantly is never cleaned so if you execute a lot of scripts containing a lot of method calls you can end up crushing the memory quickly.

Clearing that cache after each script should already help a lot (at the potential expense of some performance but, as I indicated above, right now I don't even see how this cache be useful in any way if the exact same method call cannot be reused...).
