Bug 63389 [projection] Do we need a folding region for the top-level type?
The Java editor is currently defining a folding region for the top-level type. I couldn't find a good use of this folding region and in particular it leads to some visual instability when hovering in the vertical rule in between methods. Therefore I suggest to not add this folding region.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/text/folding/DefaultJavaFoldingStructureProvider.java
private IJavaElement fJavaElement;
		private boolean fIsComment;
		public JavaProjectionAnnotation(IJavaElement element, boolean isCollapsed, boolean isComment) {
			super(isCollapsed);
			fJavaElement= element;
			fIsComment= isComment;
		}
		public IJavaElement getElement() {
			return fJavaElement;
		}
		public void setElement(IJavaElement element) {
			fJavaElement= element;
		}
		public boolean isComment() {
			return fIsComment;
		}
		public void setIsComment(boolean isComment) {
			fIsComment= isComment;
		}
		/*
		 * @see java.lang.Object#toString()
		 */
		public String toString() {
			return "JavaProjectionAnnotation:\n" + 
					"\telement: \t"+fJavaElement.toString()+"\n" + 
					"\tcollapsed: \t" + isCollapsed() + "\n" + 
					"\tcomment: \t" + fIsComment + "\n"; 
		}
