With a concurrent/multithreaded architecture, some crashes (bugs) can be only analyzed with a full backtrace of all threads, to see their interactions.

Currently hs_err file only shows a backtrace of the thread that crashed, which often necessitates that the user tries to repeat the bug locally with a debugger attached, so that we get the full picture of all threads backtrace.

It would be very helpful if hs_err file showed backtrace of all the threads.

For an example of an investigation of a bug that would benefit from this enhancement see JDK-8206471
