BeanUtils getDisposablePoolSession creates multiple lazy jcr sessions for one and the same query for a single request

Reproduction:

In testsuite trunk, in FacetedDetail java component:

After

ProductBean product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);

add

product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);
product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);
product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);
product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);
product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);
product = BeanUtils.getFacetedNavigationResultDocument(request, hstQuery, getObjectConverter(), ProductBean.class);

This will result in
