enviroment: Sun jdk1.4.2_04 on Windows 2000 Server For eclipse v3.0: When an "assert" statement is used in a java code, and the JDK compliance is set to 1.4 (in order to enable the "assert" feature), the refactory function is not available. Please see the screenshot at: http://www.javaworld.com.tw/jute/upload/2004/06/29/65845852.gif For eclipse v2.1.3: When an "assert" statement is used in a java code, and the JDK compliance is set to 1.4 (in order to enable the "assert" feature), the refactory function doesn't work. Please see picture: http://www.javaworld.com.tw/jute/upload/2004/06/24/97320716.gif There is no response after clicking on "Rename..." in the picture.
Only setting the Compliance Level to 1.4 is enough. To get assert support you have to set the source and class file compatibility to 1.4 as well (uncheck "Use defautl compliance level). I tested it with public class A { public static void main(String[] args) { assert (true) : "Testing"; } public void foo() { assert (true) : "Testing"; } } and it works. But please note that you can't rename main method.
There must be some different settings between yours and my environment. I did the same configurations (for both v.2.1.3 and v.3.0) as you did: Set the Compliance Level to 1.4 and set the source and class file compatibility to 1.4 as well (uncheck "Use defautl compliance level). But I still have the problem with refactoring. Please let me know if you need any further info from my side in order to assist you to reproduce this bug. Thanks. By the way, of course we can rename the "main" method. If you cannot rename it with your eclipse, then it is probably a bug.
Here shows the error messages in the .log file (of eclipse v. 3.0) when trying to use the refactoring feature (via right-clicking through the method name). ================================================================== !ENTRY org.eclipse.ui 4 0 六月 29, 2004 11:19:04.323 !MESSAGE java.lang.IllegalArgumentException !STACK 0 java.lang.IllegalArgumentException at org.eclipse.jdt.core.dom.ASTNode.setSourceRange(ASTNode.java:2587) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:1894) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:1810) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:770) at org.eclipse.jdt.core.dom.ASTConverter.buildBodyDeclarations(ASTConverter.java:336) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:274) at org.eclipse.jdt.core.dom.ASTConverter.convert(ASTConverter.java:152) at org.eclipse.jdt.core.dom.ASTParser.convert(ASTParser.java:711) at org.eclipse.jdt.core.dom.ASTParser.internalCreateAST(ASTParser.java:681) at org.eclipse.jdt.core.dom.ASTParser.createAST(ASTParser.java:574) at org.eclipse.jdt.internal.ui.javaeditor.ASTProvider.createAST(ASTProvider.java:439) at org.eclipse.jdt.internal.ui.javaeditor.ASTProvider.getAST(ASTProvider.java:391) at org.eclipse.jdt.internal.ui.javaeditor.JavaTextSelection.resolvePartialAstAtOffset(JavaTextSelection.java:94) at org.eclipse.jdt.internal.ui.javaeditor.JavaTextSelection.resolveSelectedNodes(JavaTextSelection.java:103) at org.eclipse.jdt.internal.ui.javaeditor.JavaTextSelection.resolveInMethodBody(JavaTextSelection.java:125) at org.eclipse.jdt.ui.actions.ExtractMethodAction.canEnable(ExtractMethodAction.java:84) at org.eclipse.jdt.ui.actions.ExtractMethodAction.selectionChanged(ExtractMethodAction.java:80) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.dispatchSelectionChanged(SelectionDispatchAction.java:202) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.update(SelectionDispatchAction.java:114) at org.eclipse.jdt.ui.actions.RefactorActionGroup.refactorMenuShown(RefactorActionGroup.java:512) at org.eclipse.jdt.ui.actions.RefactorActionGroup.access$1(RefactorActionGroup.java:497) at org.eclipse.jdt.ui.actions.RefactorActionGroup$1.menuAboutToShow(RefactorActionGroup.java:451) at org.eclipse.jface.action.MenuManager.fireAboutToShow(MenuManager.java:286) at org.eclipse.jface.action.MenuManager.handleAboutToShow(MenuManager.java:370) at org.eclipse.jface.action.MenuManager.access$0(MenuManager.java:367) at org.eclipse.jface.action.MenuManager$2.menuShown(MenuManager.java:383) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:116) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:796) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:820) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:801) at org.eclipse.swt.widgets.Control.WM_INITMENUPOPUP(Control.java:3320) at org.eclipse.swt.widgets.Control.windowProc(Control.java:2993) at org.eclipse.swt.widgets.Decorations.windowProc(Decorations.java:1391) at org.eclipse.swt.widgets.Display.windowProc(Display.java:3338) at org.eclipse.swt.internal.win32.OS.TrackPopupMenu(Native Method) at org.eclipse.swt.widgets.Menu._setVisible(Menu.java:222) at org.eclipse.swt.widgets.Display.runPopups(Display.java:2798) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2425) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1377) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1348) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:254) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:141) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:96) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:335) 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(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.core.launcher.Main.basicRun(Main.java:183) at org.eclipse.core.launcher.Main.run(Main.java:644) at org.eclipse.core.launcher.Main.main(Main.java:628)
Regarding renaming the "main" method. We can do it in v. 2.1.3 but cannot do it in v. 3.0.
This is a dup of 68823. The problem is that the AST creation fails, hence no refactoring is available. Please provide steps to reproduce the problem (best would be source code showing the problem).
