* On the other hand, the {@link
org.eclipse.aether.util.version.UnionVersionRange} is universal implementation
of
* "unions" of various {@link org.eclipse.aether.version.VersionRange}
instances.

+ * <h1>Generic Version Spec</h1>
+ * Version string is parsed into version according to these rules below:
+ * <ul>
+ * <li>The version string is parsed into segments, from left to right.</li>
+ * <li>Segments are explicitly delimited by single {@code "." (dot)},
{@code "-" (hyphen)} or {@code "_" (underscore)} character.</li>
+ * <li>Segments are implicitly delimited by transition between digits and
non-digits.</li>
+ * <li>Segments are classified as numeric, string, qualifiers (special
case of string) and min/max.</li>
+ * <li>Numeric segments are sorted numerically, ascending.</li>
+ * <li>Non-numeric segments may be qualifiers (predefined) or strings
(non-empty letter sequence). All of them are interpreted as being
case-insensitive in terms of the ROOT locale.</li>
+ * <li>Qualifier segments (strings listed below) and their sort order
(ascending) are:
+ * <ul>
+ * <li>"alpha" (== "a" when immediately followed by number)</li>
+ * <li>"beta" (== "b" when immediately followed by number)</li>
+ * <li>"milestone" (== "m" when immediately followed by
number)</li>
+ * <li>"rc" == "cr" (use of "cr" is discouraged)</li>
+ * <li>"snapshot"</li>
+ * <li>"ga" == "final" == "release"</li>
+ * <li>"sp"</li>
+ * </ul>
+ * </li>
+ * <li>String segments are sorted lexicographically, per ROOT locale,
ascending.</li>
+ * <li>There are two special segments, {@code "min"} and {@code "max"},
they represent absolute minimum and absolute maximum in comparisons.</li>
+ * <li>As last step, trailing "zero segments" are trimmed. Similarly,
"zero segments" positioned before numeric and non-numeric transitions (either
explicitly or implicitly delimited) are trimmed.</li>
+ * <li>When trimming, "zero segments" are qualifiers {@code "ga"}, {@code
"final"}, {@code "release"} only if being last (right-most) segment, empty
string and "0" always.</li>

Unsure what the problem is, but your example works as you expect, see
