According to JEP 322 (https://openjdk.java.net/jeps/322):

    If an implementor assigns a vendor version string of, e.g., 18.9 to a JDK 11 LTS build then it would be displayed:

    $ java --version
    openjdk 11 2018-09-20 LTS
    OpenJDK Runtime Environment 18.9 (build 11+42-LTS)
    OpenJDK 64-Bit Server VM 18.9 (build 11+42-LTS, mixed mode)
    $

OpenJDK:

    $./jdk-11/bin/java -version
    openjdk version "11" 2018-09-25
    OpenJDK Runtime Environment 18.9 (build 11+28)
    OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)

This is correct. OpenJDK builds from Oracle should never say "LTS".


Oracle JDK:

    $./jdk-11/bin/java -version
    java version "11" 2018-09-25
    Java(TM) SE Runtime Environment 18.9 (build 11+28)
    Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11+28, mixed mode)

Since Oracle JDK 11 is an LTS release, the "LTS" identifier should be added to the Oracle JDK build only.
