Using 200412140800, I got the following exception: java.lang.NullPointerException at org.eclipse.jdt.internal.codeassist.SelectionEngine.selectFrom(SelectionEngine.java:795) at org.eclipse.jdt.internal.codeassist.SelectionEngine.select(SelectionEngine.java:714) at org.eclipse.jdt.internal.core.Openable.codeSelect(Openable.java:140) at org.eclipse.jdt.internal.core.CompilationUnit.codeSelect(CompilationUnit.java:300) at org.eclipse.jdt.internal.core.CompilationUnit.codeSelect(CompilationUnit.java:294) at org.eclipse.jdt.internal.ui.javaeditor.JavaElementHyperlinkDetector.detectHyperlinks(JavaElementHyperlinkDetector.java:73) at org.eclipse.jface.text.hyperlink.HyperlinkManager.findHyperlinks(HyperlinkManager.java:235) at org.eclipse.jface.text.hyperlink.HyperlinkManager.mouseMove(HyperlinkManager.java:422) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:144) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:833) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:2803) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2448) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1569) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1540) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:285) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:144) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:102) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:220) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:273) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:129) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:85) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:58) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:60) at java.lang.reflect.Method.invoke(Method.java:391) at org.eclipse.core.launcher.Main.basicRun(Main.java:185) at org.eclipse.core.launcher.Main.run(Main.java:684) at org.eclipse.core.launcher.Main.main(Main.java:668) Steps to reproduce: 1) Create a new Java project 2) Set the compiler compliance to 1.5 3) Create a new compilation unit that contains: public class ShortcutIfElse { public ShortcutIfElse() { } public Integer[] getTypes() { List<Integer> list = new ArrayList<Integer>(); return list == null ? new Integer[0] : list.toArray(new Integer[list.size()]); } public static void main(String[] args) { Class clazz = null; try { clazz = Class.forName("ShortcutIfElse"); } catch (Throwable e) { e.printStackTrace(); } } } ArrayList and List are reported as errors. 3) Code assist behind ArrayList to add a import. 4) Do the same for List and you should get the NPE.
