When I open Eclipse Java EE x64 on Mac OS X El Capitan (10.11.6) then the CPU consumption goes crazy while I actually do nothing. The CPU consumption stays high as long as Eclipse is running, which means that my Mac's fan goes crazy very soon after Eclipse is started. Furthermore, the only way to exit Eclipse is by killing the process because closing Eclipse the normal way will hide the window but Eclipse never stops. I have the latest Glassfish Tools installed from the marketplace. Other than that I have a multi module maven project: ear, ejb, jar, war. I have just now discovered that when I close the projects then eclipse keeps working just fine - so there is no high CPU consumption then. As soon as I open the projects the CPU usage rapidly increases and I have the same issues again… I always have to kill eclipse and I typically send the crash repots to Apple… I have also tried to uninstall the Glassfish Tools and see what happens, but I cannot see any change at all - so the Glassfish Tools are not causing the issue. I have also downloaded Eclipse again and again and I always used clean workspaces. However, even this did not help. My colleague has the same issue on his MacBook Pro 2016 with the latest version of macOS and using the same multi module maven project. This makes me believe that there is some other issue with the „out of the box“ Eclipse Java EE package which is related to multi module maven projects. Because of this Eclipse is not usable for us (we’re using other IDEs for now). Unfortunately, I cannot easily offer you our maven project... Any idea? I tried everything I have no clue what else I should try. -- Configuration Details -- Product: Eclipse 4.6.3.20170314-1500 (org.eclipse.epp.package.jee.product)Installed Features: org.eclipse.jdt 3.12.3.v20170301-0400 Versioning Plugin: org.eclipse.platform 4.6.3.v20170301-0400
Please create few jstack dumps while Eclipse is busy and attach them here.
Created attachment 268566 [details] jstack dumps I just attached the stack dumps. I took them for 2 different situations: 1. I opened eclipse and while doing exactly nothing 2. Closing Eclipse (i.e. with Cmd + q)
I'm experiencing the same symptoms with Eclispe 2018-12 and macOS Mojave on a MacBook Pro (2018). Also, the MacBooks fans go crazy and never stops; battery drains quickly. How can I create jstack dumps to attach them here?
