On the SolarisTM Operating System (Solaris OS), after clicking Next on the Choose Software Components page you might see the following page regarding the Java 2 Software Development Kit, Standard Edition (J2SE SDK).
This page is displayed if the installer detects an incompatible system-wide version of the J2SE SDK. Keep the default selection of an automatic upgrade, which brings the version up to date.
If the installer encounters a higher version of the JDK and one or more JDK packages are missing (for example, the 64–bit JVMTM software), the installer treats this version as incompatible. In that case, when you keep the automatic upgrade option the JDK is downgraded to the version of the JDK required by Java ES.
