BTW, this is our own subclass for LDM. The reported size of 32/24 is for a pure LDM of course different (and not measured here).

Exact same scenario followed for these two sessions: with boolean (current Wicket LDM): 330661 object live, shallow size 18,025,792, retained: 18,025,792 51 LDM instances, shallow size 1624, retained: 1,704 without boolean (custom LDM): 330438 objects live, shallow size 17,790,424, retained 17,790,424 51 LDM instances, shallow size 1,224, retained 1,304 The shallow size of a LDM instance went from 32 bytes to 24 bytes. I think this is worth the change.
