I had too many issues removing bodies during game play even with everything happening via runOnUpdateThread I would still get random body removal errors - I gave up on destroying bodies and set them to active/inactive as needed now.

It's a good idea to use pools to avoid wasting resources.

Edit: Also be aware that you can not destory bodies in the physical world contact handlers - you need to either perform the deletes using runOnUpdateThread() or via flags and some logic in an new/existing update handler.

Like OzLark says there are problems with body removal and creation even if you do it right. I had them for the longest time(I don't even want to count how many times I got the linker errors due to physics failing.) But in the end, shani you are too quick to discard OzLarks suggestion. Setting an inactive setting is much faster and safer. What I do is set bodies meant for deletion to inactive and then delete them on update thread.
