Debug adapter does not terminate the debugged process in 0.59 (works in 0.58.5) #628

I'm using the debug adapter to debug Java code using Neovim. Everything was working very well in 0.58.5 but when I upgraded to 0.59 it is no longer possible to terminate the debug session. The java process being debugged simply remains running. Reverting back to 0.58.5 fixes the problem. I don't think this is anything Neovim specific but a recently introduced bug.
