The OOM at Jenkins is of a particular kind - "unable to create native
thread" (different from "OutOfMemoryError Java Heap Space") which means the
stack associated with a thread could not be allocated. The thread stack is
not allocated on the heap. So heap size is immaterial is such OOM error.
(this can be confirmed by setting -XX:+HeapDumpOnOutOfMemoryError
<> and
verifying the occupied heap from the dump.

Though stack size for a thread can be configured (-Xss) but I don't think
we should fiddle with it.

Ian, do you know what has been the corresponding number of threads from
previous stable builds?
