Description

When using @XPath() annotations to bean method parameters, XPathBuilder is used and expressions are added to a pool in the init() method of the class.

These expressions are keep adding up but they are never cleared.

There's a method doStop() which has the code for cleaning but it is never used, hence a leakage of XPathExpressions.
