>     I found a puzzling case of the HIR. The attachment is the picture of the HIR. In
this pictrue, the control flows along the 2 in-edges of Node 98(the node whose id is 98) seem
to have different lock state.The control flow from the left in-edge is unlocked at the end
of Node 102, but the control flow from the right in-edge is not unlocked. Because if exception
has been thrown then the last monexit of Node 102 will not been executed.
>     Is this case legal? Or I missed something else?
