@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.

Since:
5.1
