With 16GB ram on my MacBookPro, I've modified my eclipse.ini to have lots of memory but editing JSP or HTML and doing a copy/paste will mostly of the time beachball and show an error dialog. Here's my eclipse.ini -startup ../../../plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.200.v20140603-1326 -product org.eclipse.epp.package.jee.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile --launcher.appendVmargs -vmargs -Dosgi.requiredJavaVersion=1.7 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:MaxPermSize=512m -Xms512m -Xmx1024m -Xdock:icon=../Resources/Eclipse.icns -Dorg.eclipse.swt.internal.carbon.smallFonts
I find the "unhandled event loop exception java heap space" mostly occurs when editing JSP content. I selected Project > Properties > JavaScript > Include Path and removed all files. Let's see how this goes.
Still crap performance. Here's my config: MacBook Pro 2.7GHz 16GB RAM Mavericks 10.9.5 with brand new Apple Thunderbolt Display 27" 2560x1440 pixels and Eclipse Java EE Luna release 4.4.0 Build 20140612-0600, Java 7 1.7.0_67 Scrolling is not great, but doable. Working with JSPs causes Eclipse to show useless spinning beachball and spiking CPU well over 100%. Totally useless. I've fiddled with my eclipse.ini but increasing the -Xmx and removing smallFonts but still not working great. What a bummer. Might be time to switch to IntelliJ.
Are you still sees it using 4.5.2 and, if so, please attach stack dumps
Now using Eclipse Java EE IDE for Web Developers Version: Mars.2 Release (4.5.2) Build id: 20160218-0600 No, I do not see this error/beachball nearly as much and Eclipse doesn't die on me like it used to.
