      "message": "Selective deoptimization.\n\nUpdate the instrumentation to allow selective deoptimization.\n\nSeparate instrumentation listener registration from stubs configuration. A\nlistener is now responsible for configuring the appropriate stubs.\n- The method tracing listener installs instrumentation entry/exit stubs or\nthe interpreter depending on the accuracy of events we want (controlled by\nkDeoptimizeForAccurateMethodEntryExitListeners).\n- The debugger registers itself as an instrumentation listener but does not\nmodify methods entrypoints. It only does this on demand when deoptimizing one\nmethod or all the methods.\n\nThe selective deoptimization is used for breakpoint only. When a breakpoint is\nrequested, the debugger deoptimizes this method by setting its entrypoint to\nthe interpreter stub. As several breakpoints can be set on the same method, we\ndeoptimize only once. When the last breakpoint on a method is removed, we\nreoptimize it by restoring the original entrypoints.\n\nThe full deoptimization is used for method entry, method exit and single-step\nevents. When one of these events is requested, we force eveything to run with\nthe interpreter (except native and proxy methods). When the last of these\nevents is removed, we restore all methods entrypoints except those which are\ncurrently deoptimized.\n\nDeoptimizing a method requires all mutator threads be suspended in order to\nwalk each thread\u0027s stack and ensure no code is actually executing while we\nmodify methods entrypoints. Suspending all the threads requires to not hold\nany lock.\nIn the debugger, we deoptimize/undeoptimize when the JDWP event list changes\n(add or remove a breakpoint for instance). During the update, we need to hold\nthe JDWP event list lock. This means we cannot suspend all the threads at this\ntime.\nIn order to deal with these constraints, we support a queue of deoptimization\nrequests. When an event needs selective/full deoptimization/undeoptimization,\nwe save its request in the queue. Once we release the JDWP event list lock, we\nsuspend all the threads, process this queue and finally resume all the threads.\nThis is done in Dbg::ManageDeoptimization. Note: threads already suspended\nbefore doing this remain suspended so we don\u0027t \"break\" debugger suspensions.\n\nWhen we deoptimize one method or every method, we need to browse each thread\u0027s\nstack to install instrumentation exit PC as return PC and save information in\nthe instrumentation stack frame. Now we can deoptimize multiple times during\nthe execution of an application, we need to preserve exisiting instrumentation\nframes (which is the result of a previous deoptimization). This require to push\nnew instrumentation frames before existing ones so we don\u0027t corrupt the\ninstrumentation stack frame while walking the stack.\n\nBug: 11538162\nChange-Id: I477142df17edf2dab8ac5d879daacc5c08a67c39\n"
