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.

		fProject= project;

		fPath= path;
