----------------------------------------
Hi guys,
@Lukasz
I totally agree with Philip, furthermore I don't believe it fixes the problem.
I have taken a deeper look at this issue last weekend. I also thought that the
internal cache could be a potential cause of memory leaks, but setting a
breakpoint on the code I realized that there were always 40 objects (not more)
inside the cache.
I ran the code example on Glassfish 3.1.1 and unfortunately I didn't experience
the problem that Marco mentioned before (I got the usual sawtooth wave).
I also changed the code using the Spring Framework, but the outcome is more or
less the same.
@Marco, I could be wrong but can you confirm the java vendor/version?
Have you experienced this issue in other environments (it could be also a
glassfish issue)?
