Since apparently you are not using many static pages, this would seem to 
rule out the bug which got fixed.

Jasper 2 introduces pooling for a lot of objects which previously 
weren't pooled, so it is a possible cause. Maybe there is a problem with 
the size of those pools, although I didn't notice anything completely 
wrong in the code.

This will need to be investigated. Overall, 4.1.x should use a little 
bit more memory than 4.0.x, but there shouldn't be a huge difference.

Note: 4.1.5 introduces more pooling (rather than less), like for tag 
instances for example, but those pools have limits on their size.
