javaw.exe often using too much CPU

pstrg · 25 May 2020

I often notice that javaw.exe (8 Update 251) is taking too much CPU (65% upwards).
Tried to investigate using Process Explorer, System Explorer, Task Manager Deluxe, Daphne, but none of them provides the information I'm looking for: which program/process is demanding Java too much.
Any help diagnosing that?

p.s. My system information in this forum is fully updated.

This is old, but maybe worth reading: What applications use Java on a desktop? - Super User

Thank you very much.
Based on your answer, I was able to find another Superuser thread and quickly found the culprit:

Why do you need Java? I have not used it in the last five years (unless an application installs it's own localized version)

Brazil tax declaration programs require Java; but they don't run on the background.

Running on the background, DuckDNS also uses Java (but just a bit).
The other background running one, which was causing the problem, is BubbleUPnP Server - but I really don't use it anymore, so no problem.
