Junior Dussouillez commented on NETBEANS-1932:
----------------------------------------------

[~Chrizzly] I have the following projects open : 
 * A maven multimodule project (pom only)
 * Submodule #0 - A Jersey REST API project
 * Submodule #1 - The "common" module (beans & DAOs)
 * Submodule #2 - A console application to generate a JAR
 * Submodule #3 - A HTML5 project (contains a pom AND a packages.json) for the 
frontend of the app (Angular 7)
 * A simple console application project with a single main class to test code

All the projects are using Maven. Unfortunately this is a company project, so I 
can't give you the sources.

I tried to isolate an action that trigger the CPU overload, but I didn't 
succeeded. It happens sometimes when editing a file, or using the "refactor" 
feature, or even if the Netbeans window is not the active one. I will continue 
to analyze the error and post updates in the comments if I find something.

 

Anyway, thanks for the project, and your reactivity !

> Since Netbeans 9.0, I get random excessive CPU load. It can happen twice a 
> day or even twice an hour. The UI does not respond and the CPU goes to 100%.
> I have to kill the netbeans process and when I start it again, I get the 
> error window (see the UI_Log.txt and IDE_Log.txt log files).
> I remain at your disposal if you need more informations.
