Claus Ibsen commented on CAMEL-17181:
-------------------------------------
Okay I found the problem is due to pre compile is enabled and that it adds to
the pool even if the pool already has an element - this is due to how @XPath
annotations works differently than when you use it in the route DSL
> camel-core - XPathBuilder never clears pool when using @XPath annotation

>
> 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.
