Switch task inside a fork-join

[parakhshrenik]

I've a use case where I've multiple switch tasks inside a fork join.

Let's assume it looks like this (pseudo code)

fork task: 
    switch task 1:
        case A: SIMPLE TASK A
        default case: SIMPLE TASK B
    switch task 2:
        case C: SIMPLE TASK C
        default case: (nothing)
join task

Now, the question I've is what should I join on? The expected behavior is the join should happen only when both the branches are done executing.

But if I JOIN_ON (TASK A & TASK C) it may never finish in case it goes to default case of either of the switch tasks.
