Hi David.
Thanks for your detailed comments.
The async-profiler has a lot of features, but there are some requirements
to use it (some cases encountered in production are listed below):
1. Prior to JDK 11, alloc mode requires HotSpot debug symbols, and for
OpenJDK, you need to install them

information, along with deeper Java & system call stack information.

One minor comment:
In general, the generic java profiler includes memory analysis,
cpu, thread, deadlock, etc. The FLIP title is java profiler, but
the FLIP just supports flamegraph at process level.
So the `powerful java profiler` title may not be suitable.
Would you mind updating the FLIP
Hi all.
If there are no further questions, we will start a vote on FLIP-375 next
week.

Hi all,
Yun Tang and I are opening this thread to discuss our proposal to integrate
async-profiler's capabilities for profiling taskmananger (e.g., generating
flame graphs) in the Flink Web [1].
Currently, Flink provides ThreadDump and Operator-Level Flame Graphs by
sampling task threads. The
