Bug 41523 Keep Order of libs when editing library [build path]
When I edit a library in the Properties dialog of my project using "Properties"->"Java Build Path"->"Libraries"->"Edit", e.g. changing the JRE from 1.4 to 1.3, or changing from an old version of a JAR to a newer one, the changed library is at the last position in the classpath. It should kept at the position it was.

public void setIsMissing(boolean isMissing) {
		fIsMissing= isMissing;
	}
	/**
	 * Returns if a entry is exported (only applies to libraries)
	 * @return Returns a boolean
	 */
	public boolean isExported() {
		return fIsExported;
	}
	/**
	 * Sets the export state of the entry.
	 */
	public void setExported(boolean isExported) {
		if (isExported != fIsExported) {
			fIsExported = isExported;
			
			attributeChanged(null);
		}
	}
	/**
	 * Gets the project.
	 * @return Returns a IJavaProject
	 */
	public IJavaProject getJavaProject() {
		return fProject;
	}
	
	public static CPListElement createFromExisting(IClasspathEntry curr, IJavaProject project) {
		IPath path= curr.getPath();
