Mikael Andersson Wigander commented on CAMEL-17181:
---------------------------------------------------
Just for my curiousity, the doStop() method in XPathBuilder.class is never
executed it seems.
In that method the Queues pool and poolLogNamespaces are clear
{code:java}
@Override
public void doStop() throws Exception {
pool.clear();
poolLogNamespaces.clear();
}
{code}
Shouldn't it be called from somewhere in Camel?
> camel-core - XPathBuilder never clears pool when using @XPath annotation and
> grows pool causing memory leak

> 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.
