I just ran a debug session and with my openocd debug plugin the assert fails 3 times, due to previous `getConsole(launch)` returning null.

the assert is triggered when the session terminates.

but looking carefully I also noticed another problem: during session startup, there are two more exceptions:

the effect is that the arm-none-eabi-gdb output is no longer visible, I can see only the openocd console.

I can enable the gdb trace console, but the main gdb console is not present.

any suggestion?
