发帖数: 886 | 1 I'm running an application on Weblogic. I did a profile of the heap, and
find out 43% of all objects in heap are Integers and they can't be cleaned up
by GC. Why these integers stay in heap? Does that indicate a memory leak? | m****r
发帖数: 11 | 2 If the heap keeps increasing, it is a memory leak. You need to check who
references
those Integers. java profilers shall provide reference graph. which profiler
are you using?

Note that unless you have -incgc turned on, the GC may not kick in until
there isn't any free memory left, i.e., you might not see these Integers
GCed even though they are not in use any more.
