On Oracle Solaris, the JDK and JRE no longer have an ISA (Instruction Specific Architecture) bin directory. The `$JAVA_HOME/bin/sparcv9` and `$JAVA_HOME/bin/amd64` directories, and the sym links in the directories, were present in JDK 8 to aid migration after 32-bit support was removed. Scripts or applications that rely on these locations should be updated to use `$JAVA_HOME/bin`.
