In a project I get the following error located in one specific java file. If I remove (move from file system) the java file from the project, save/compile the project and then add the file to the project again the error is gone and the java file compiles (a *.class file is generated) until I recompile the whole project, then the error is back... The error appears in both Eclipse 3.1M4 and 3.1M5a The java file is compile-able using javac in a command prompt.

Could you please attach your project for further investigation?
I'm afraid my project is confidential because of business reasons... :-( I investigated this problem further and pin pointed the lines of code Eclipse "didn't like". I have no idea why it didn't like them but I found a work around by changing a method argument type to another type. You can close this bug report as far as I'm concerned. Many thanks!
No, we have a bug. Could you please try to isolate a test case that would reproduce this issue?
I would really encourage you to spend a few minutes trying to isolate a testcase, if not the bug will remain.
Are you using static imports in your code ?
(In reply to comment #5) > Are you using static imports in your code ? Actually, I am. Or was... I don't have the code in front of me right now but I did do some static imports for a static enum from another class. I will try to see if I can reproduce this error by adding these static imports again tomorrow. Cheers -Martin
I tried something like that, in vain... but maybe you can find a common pattern: import static p.ST.foo; public class X { foo bar; } package p; public class ST { static int foo; }
Created attachment 18675 [details] Test case I reproduced the problem with a small test case. Steps to reproduce: 1) Unzip the attachment on your disk 2) Create a project that points to the project you just extracted 3) Do a full build 4) This should work. 5) Add a space in Y.java and recompile. You should end up with the following stack trace: Exception in thread "Text Viewer Hover Presenter" java.lang.ClassCastException: org.eclipse.jdt.internal.compiler.lookup.FieldBinding at org.eclipse.jdt.internal.compiler.lookup.Scope.getType(Scope.java:2132) at org.eclipse.jdt.internal.compiler.ast.SingleTypeReference.getTypeBinding(SingleTypeReference.java:39) at org.eclipse.jdt.internal.compiler.ast.TypeReference.resolveType(TypeReference.java:141) at org.eclipse.jdt.internal.compiler.ast.TypeReference.resolveSuperType(TypeReference.java:104) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.findSupertype(ClassScope.java:1051) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.connectSuperInterfaces(ClassScope.java:790) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.connectTypeHierarchy(ClassScope.java:847) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.connectTypeHierarchy(CompilationUnitScope.java:243) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.completeTypeBindings(LookupEnvironment.java:249) at org.eclipse.jdt.internal.codeassist.SelectionEngine.select(SelectionEngine.java:713) 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.text.java.hover.AbstractJavaEditorTextHover.getHoverInfo(AbstractJavaEditorTextHover.java:108) at org.eclipse.jdt.internal.ui.text.java.hover.BestMatchHover.getHoverInfo(BestMatchHover.java:102) at org.eclipse.jdt.internal.ui.text.java.hover.JavaEditorTextHoverProxy.getHoverInfo(JavaEditorTextHoverProxy.java:69) at org.eclipse.jface.text.TextViewerHoverManager$4.run(TextViewerHoverManager.java:160) It is not exactly the same one, but I believe this is the same problem.
Glad you reproduced it olivier. Made a fix, Kent pls verify it. Added StaticImportTest#test028. Martin - if you take next nightly build, you should be able to prove it addresses your problem.
fixed
Glad to see you fixed this!
