Created attachment 413412 [details] Enable bytecode cache testing on Linux, v3 v3, do not use arrays in the shell script, that way it will work in any POSIX shell. This was the error in some of the EWS bots in the end (which use 'dash').
Created attachment 413579 [details] Enable bytecode cache testing on Linux, v4 v4, skip on MIPS until bug #218703 is fixed and we make the bots a bit faster.
