I've noticed that some of my enums fail to parse within Eclipse (3.1 11/2/04
integration build).  After opening or while moving the cursor around within an
offending file, I repeatedly get a dialog stating:
'An internal error occurred during: "Java AST creation".'

Associated with this error I get following exception in the error log:
java.lang.ClassCastException: org.eclipse.jdt.internal.compiler.ast.TypeDeclaration
	at org.eclipse.jdt.core.dom.ASTConverter.lookupScope(ASTConverter.java:3416)

I believe the error occurs when an enum references static vars defined in other
types from within its static initializer (there may be other cases).  I've
managed to come up with a reproducible test case, which I've pasted below.  Put
the two type definitions in two separate .java files in a project.  Then open
Test.java.  After opening, click somewhere within the body of the enum.  This
should reproduce the error.

public enum Test {
    VAL_A;

    private static final String VAL_A_LABEL;

    static {
        VAL_A_LABEL = Test2.value;
    }
}

public class Test2 {   
    public static final String value = "foo";
}
