@API(status=STABLE, since="5.1") public enum JRE extends Enum<JRE>
Enumeration of Java Runtime Environment (JRE) versions.
If the current JRE version cannot be detected — for example, if the
java.version
JVM system property is undefined — then none of
the constants defined in this enum will be considered to be the
current JRE version.
