At this point it's quite possible that you still have a reference to newData in a register.
That argument works for one iteration, but this fool just keeps on growing. Also, this is a pared down test from a much larger program, so this is unlikely.
If you want to be sure the collect call below works as intended for this test, try adding:newData = new Data; here.i = 0; GC.collect(); } }
Nope, didn't do anything. It still swells forever.
Beyond that, you'll just potentially end up with a bunch of false positives, since you have a big static array in the same block as a pointer. But since you aren't actually setting the array contents in this test, that clearly isn't a problem here.
The real program is a tree structure that contains class references, so is entirely pointers. The root of the tree is then discarded, and a new tree created, however the old tree isn't being collected.
