Just installed NetBeans 15, everything was running well until I started bumping into this error, it’s happened two or three times now.
I have not managed to reliably recreate it as yet - as soon as I can I will make a video, but essentially; I have a block of code similar to this; >> Optional.ofNullable(blah).ifPresent(b -> b.doSomething()); When I do something like; >> Optional.ofNullable(blah).map()ifPresent(b -> b.doSomething()); i.e. the new code is in progress but the editor throws this error and I can no longer type inside the function. If I back out the map and make the code correct, the editor still does not respond to new characters. Other parts of the editor respond. If I then hit enter before the point where I was making the edit in the now correct syntax I can now type again. Closing the file also clears the problem. java.lang.NullPointerException: Cannot invoke "org.netbeans.lib.editor.codetemplates.textsync.TextRegion.regions()" because "parent" is null at org.netbeans.lib.editor.codetemplates.textsync.TextRegionManager.fixRegionStartOffset(TextRegionManager.java:877) at org.netbeans.lib.editor.codetemplates.textsync.TextRegionManager.insertUpdate(TextRegionManager.java:600) at org.netbeans.lib.editor.codetemplates.textsync.TextRegionManager$DocListener.insertUpdate(TextRegionManager.java:1104) at org.netbeans.editor.BaseDocument.handleInsertString(BaseDocument.java:845) at org.netbeans.editor.BaseDocument$FilterBypassImpl.insertString(BaseDocument.java:2643) at java.desktop/javax.swing.text.DocumentFilter.insertString(DocumentFilter.java:105) at org.openide.text.CloneableEditorSupport$DocFilter.insertString(CloneableEditorSupport.java:2340) at org.netbeans.editor.BaseDocument.insertString(BaseDocument.java:741) at org.netbeans.editor.BaseKit$DefaultKeyTypedAction.insertString(BaseKit.java:1324) at org.netbeans.editor.BaseKit$DefaultKeyTypedAction.performTextInsertion(BaseKit.java:1397) at org.netbeans.editor.BaseKit$DefaultKeyTypedAction.access$100(BaseKit.java:1052) at org.netbeans.editor.BaseKit$DefaultKeyTypedAction$3.run(BaseKit.java:1256) at org.netbeans.editor.GuardedDocument.runAtomicAsUser(GuardedDocument.java:333) at org.netbeans.editor.BaseKit$DefaultKeyTypedAction.actionPerformed(BaseKit.java:1231) at org.netbeans.editor.ext.ExtKit$ExtDefaultKeyTypedAction.actionPerformed(ExtKit.java:1055) at org.netbeans.editor.BaseAction.actionPerformed(BaseAction.java:322) at java.desktop/javax.swing.SwingUtilities.notifyAction(SwingUtilities.java:1810) at java.desktop/javax.swing.JComponent.processKeyBinding(JComponent.java:2956) at java.desktop/javax.swing.JComponent.processKeyBindings(JComponent.java:3004) at java.desktop/javax.swing.JComponent.processKeyEvent(JComponent.java:2918) at java.desktop/java.awt.Component.processEvent(Component.java:6393) at java.desktop/java.awt.Container.processEvent(Container.java:2266) at java.desktop/java.awt.Component.dispatchEventImpl(Component.java:4991) at java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2324) at java.desktop/java.awt.Component.dispatchEvent(Component.java:4823) at java.desktop/java.awt.KeyboardFocusManager.redispatchEvent(KeyboardFocusManager.java:1952) at java.desktop/java.awt.DefaultKeyboardFocusManager.dispatchKeyEvent(DefaultKeyboardFocusManager.java:883) at java.desktop/java.awt.DefaultKeyboardFocusManager.preDispatchKeyEvent(DefaultKeyboardFocusManager.java:1146) at java.desktop/java.awt.DefaultKeyboardFocusManager.typeAheadAssertions(DefaultKeyboardFocusManager.java:1020) at java.desktop/java.awt.DefaultKeyboardFocusManager.dispatchEvent(DefaultKeyboardFocusManager.java:848) at java.desktop/java.awt.Component.dispatchEventImpl(Component.java:4872) at java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2324) at java.desktop/java.awt.Window.dispatchEventImpl(Window.java:2780) at java.desktop/java.awt.Component.dispatchEvent(Component.java:4823) at java.desktop/java.awt.EventQueue.dispatchEventImpl(EventQueue.java:775) at java.desktop/java.awt.EventQueue$4.run(EventQueue.java:720) at java.desktop/java.awt.EventQueue$4.run(EventQueue.java:714) at java.base/java.security.AccessController.doPrivileged(AccessController.java:399) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:86) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:97) at java.desktop/java.awt.EventQueue$5.run(EventQueue.java:747) at java.desktop/java.awt.EventQueue$5.run(EventQueue.java:745) at java.base/java.security.AccessController.doPrivileged(AccessController.java:399) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:86) at java.desktop/java.awt.EventQueue.dispatchEvent(EventQueue.java:744) 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) Associate Principal Engineer | UK Development - Care Insight and Delivery Dev | [email protected]<mailto:[email protected]> | Oracle Cerner CONFIDENTIALITY NOTICE This message and any included attachments are from Cerner Corporation and are intended only for the addressee.
