The release notes for the 32-bit removal needs more explanation of the changes, the following
needs to be added:

> The 32-bit implementation of Java for the Solaris operating system has been removed from this release.

The 32-bit implementation of Java for Solaris operating system has been removed from this release, thus $JAVA_HOME/bin and $JAVA_HOME/jre/bin contains the 64-bit specific binaries, for transitional purposes
the ISA (Instruction Specific Architecture) directories, $JAVA_HOME/bin/{sparcv9,amd64} and $JAVA_HOME/jre/{sparcv9,amd64} now contain symbolic links pointing to the binaries.

Note that the ISA directory is provided for compatibility and transitional purposes in JDK8 and will be removed in JDK9.

The install packages SUNWj8rt, SUNWj8dev and SUNWj8dmo contains the 64-bit binaries previously
they contained 32-bit binaries, the 64-bit specific packages SUNWj8rtx, SUNWj8dvx and SUNWj8dmx have been removed. Since only 64-bit binaries are supported the binaries no longer contain deployment tools
such as the Java Webstart and Java Plugin, therefore all desktop integration is no longer required.
