async-profiler can't find process by name when CPU is overloaded

[gladko]

trying to profile same simplest app as described in #852 but this time CPU burning activity is executed in ~15 threads and consumes all CPU.

1. run jps to see running JVM

% jps                               
...
36742 PerfTestManager

2. profiling

% profiler.sh -d 300 PerfTestManager
No Java process 'PerfTestManager' could be found!
Usage: /Users/vladimirkozak/workspace/tools/async-profiler-2.9-macos/profiler.sh [action] [options] <pid>
Actions:
  start             start profiling and return immediately
 ...

3. run jps to see running JVM again and check if target process is still alive

% jps
...
36742 PerfTestManager

Can you try with async-profiler 3.0-ea or with an up-to-date version from master?
It has major changes in the launcher, including the way how the target process is discovered.

[gladko]

can't reproduce it on master async-profiler

Thanks for confirming it works with the latest async-profiler.
