Intended to be. Removing "bash" doesn't fix the problem. I tried that before.
We followed what ADT did. Lianhao told me when the user needs to launch qemu to debug in ADT Eclipse plugin, the ADT team uses xterm, since that is the minimal terminal. So I didn't investigate other approaches but stood on the shoulder of the ADT team.

I suspect that will occur on ADT's side. Jessica, Lianhao, do you have better solution?

Yes.

Is matchbox-terminal the minimal terminal on Linux distributions, compared with xterm? If so, we can replace xterm with that.
Yes, we can, feature enhancement.

I see. My concern is whether matchbox-terminal is available on Ubuntu/Fedora/OpenSuse/CentOS, and so on.
