DT script provides the way for users to install the latest available jre version
via deployJava.installLatestJRE()

However, as the current development JREs version become widely available to users, this "latest" JRE version needs to be re-considered. In other words, if users have the later jre version than the defined public latest version, they end up to get the older version via deployJava.installLatestJRE()

E.g: (as of the time of this CR written, jre 7u5 is the public latest version)

1) Case 1: jre 7u6 existed on the system
Invoke deployJava.installLatestJRE() will install static jre 7u5

2) Case 2: jre 8 existed on the system
Invoke deployJava.installLatestJRE() will install jre 7u5

3) Case 3: jre 7u5 existed on the system
Invoke deployJava.installLatestJRE() will notify the version already installed and offer to re-install
