JVM crashes in JIT compiled code without hs_err_pid file

[Alexandr Miloslavskiy]

I noticed that a number of foreign DLLs were loaded in the process when 
it crashed:

C:\Program 
Files\DGAgent\plugins\09D849B6-32D3-4A40-85EE-6B84BA29E35B\AE_MailSensor_Plugin64.dll
C:\Program 
Files\DGAgent\plugins\09D849B6-32D3-4A40-85EE-6B84BA29E35B\ame_outlooksensor64.dll
C:\Program 
Files\DGAgent\plugins\09D849B6-32D3-4A40-85EE-6B84BA29E35B\ame_smtpsensor64.dll
C:\Program 
Files\DGAgent\plugins\8E4EA70A-6128-4B57-BD3F-8E9E0F0DA6BB\COM_Sensor64.dll
C:\Program 
Files\DGAgent\plugins\8E4EA70A-6128-4B57-BD3F-8E9E0F0DA6BB\OS_Plugin64.dll
C:\Program Files\FileZilla FTP Client\fzshellext_64.dll
C:\ProgramData\Symantec\Symantec Endpoint 
Protection\14.3.8268.5000.105\Data\Sysfer\x64\sysfer.dll

I told user to get rid of these. He says that he put our application 
into exclusion list in "Symantec Endpoint Protection" and so far there 
were no crashes.

If true, I still wonder how exactly does it manage to break things.
