public class VersionComparator
extends java.lang.Object
implements java.util.Comparator<java.lang.String>
Comparator for version strings.
SNAPSHOT items always lowest rated, then splitting on dots, using natural order comparator (so "9" < "10" and "4u8" < "4u20"), and preferring segments without qualifiers ("4" > "4beta").
Impossible to follow semantics for all versioning schemes but does the obvious right thing for normal schemes and pretty well in fringe cases.
See test case for lots of examples.
