[EBZ#522181] ------------------------------------------------------------------------------------------ Key: ERT-536 URL: https://issues.jboss.org/browse/ERT-536 Project: Eclipse Release Train Issue Type: Task Components: Platform Reporter: Friendly Jira Robot Assignee: Roland Grunberg Labels: SWT, bzira Created attachment 270164 hs_err_pid20835.log Build ID: 20170907-1650_eclipse-cpp-oxygen-1-RC3-linux.gtk.x86_64.tar.gz Host: Ubuntu 16.04.2 on Virtualbox 5.1.26, 3D acceleration + guest utilities on GTK: libwebkit2gtk-4.0-37:amd64 2.16.6-0ubuntu0.16.04.1 Eclipse crashed hard on me with attached hs_err_pid20835.log , here are the top frames from the stack: Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) j org.eclipse.swt.internal.webkit.WebKitGTK._webkit_get_default_session()J+0 j org.eclipse.swt.internal.webkit.WebKitGTK.webkit_get_default_session()J+7 j org.eclipse.swt.browser.WebKit.lambda$0()V+7 j org.eclipse.swt.browser.WebKit$$Lambda$328.run()V+0 j org.eclipse.swt.browser.WebBrowser.clearSessions()V+9 j org.eclipse.swt.browser.Browser.clearSessions()V+0 j org.eclipse.oomph.ui.HelpSupport.setHelpPath(Ljava/lang/String;)V+31 j org.eclipse.oomph.ui.HelpSupport.updateHelp()V+11 The issue is not reproducible, but here's the steps I had performed: 1. Launch Eclipse, close the welcome screen (Note: Welcome screen is empty) 2. Import a C/C++ project, allow it to be fully indexed 3. Launch a GDB debug session 4. Window > Preferences, enable the Oomph Preference Recorder 5. Preferences:Filter:GDB, Enable "GDB Traces", click "Apply and Close" --> The Oomph confirmation dialog briefly appeared --> Then an Ubuntu dialog said "WebKitNetworkProcess died" and Eclipse was gone
