An exception icon has appeared and the IDE became > unresponsive for several minutes, not as much as to invoke the Windows' > WerFault dialog though, the mouse cursor has changed according to the area > (editor vs other UI), but I couldn't click anything, the UI appeared frozen > otherwise. > I don't know if it's related to the update, but it didn't happen before. > I was looking for text occurrences in a file (using Ctrl+F), then I must have > invoked some action shortcut by mistake because the content of the file have > changed - there used to be a normal assignment (disregard the editor cursor > position though, it has changed during my attempts to click anywhere): > !Annotation 2020-07-23 115255.png! > After some time the IDE became responsive again, but froze shortly after that > for some more time. It has been in such state until I closed it. By then it > has gradually consumed around 9 GB of RAM :) > I was able to take a profiler snapshot and extract the exception details and > UI/IDE logs during the moments when the IDE was responsive, see the > attachments. > Stack trace: > {code} > java.lang.NullPointerException at > java.desktop/javax.swing.text.JTextComponent.write(JTextComponent.java:1655) > at java.desktop/javax.swing.JEditorPane.getText(JEditorPane.java:1451) at > org.netbeans.modules.editor.search.SearchBar.showNumberOfMatches(SearchBar.java:1039) > at > org.netbeans.modules.editor.search.SearchBar$13.caretUpdate(SearchBar.java:502) > at > java.desktop/javax.swing.text.JTextComponent.fireCaretUpdate(JTextComponent.java:412) > at > java.desktop/javax.swing.text.JTextComponent$MutableCaretEvent.fire(JTextComponent.java:4489) > at > java.desktop/javax.swing.text.JTextComponent$MutableCaretEvent.mouseReleased(JTextComponent.java:4545) > at > java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) > at > java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) > at > java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) > at > java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) > at > java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) > at > java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) > at java.desktop/java.awt.Component.processMouseEvent(Component.java:6632) at > java.desktop/javax.swing.JComponent.processMouseEvent(JComponent.java:3342) > at java.desktop/java.awt.Component.processEvent(Component.java:6397) at > java.desktop/java.awt.Container.processEvent(Container.java:2263) at > java.desktop/java.awt.Component.dispatchEventImpl(Component.java:5008) at > java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2321) at > java.desktop/java.awt.Component.dispatchEvent(Component.java:4840) at > java.desktop/java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4918) > at > java.desktop/java.awt.LightweightDispatcher.processMouseEvent(Container.java:4547) > at > java.desktop/java.awt.LightweightDispatcher.dispatchEvent(Container.java:4488) > at java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2307) at > java.desktop/java.awt.Window.dispatchEventImpl(Window.java:2762) at > java.desktop/java.awt.Component.dispatchEvent(Component.java:4840) at > java.desktop/java.awt.EventQueue.dispatchEventImpl(EventQueue.java:772) at > java.desktop/java.awt.EventQueue$4.run(EventQueue.java:721) at > java.desktop/java.awt.EventQueue$4.run(EventQueue.java:715) at > java.base/java.security.AccessController.doPrivileged(AccessController.java:389) > at > java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:85) > at > java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:95) > at java.desktop/java.awt.EventQueue$5.run(EventQueue.java:745) at > java.desktop/java.awt.EventQueue$5.run(EventQueue.java:743) at > java.base/java.security.AccessController.doPrivileged(AccessController.java:389) > at > java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:85) > at java.desktop/java.awt.EventQueue.dispatchEvent(EventQueue.java:742) at > org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:136) > [catch] at > java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:203) > at > java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:124) > at > java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:113) > at > java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:109) > at > java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) > at java.desktop/java.awt.EventDispatchThread.run(EventDispatchThread.java:90) > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@netbeans.apache.org For additional commands, e-mail: commits-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
