Check to see whether an executable jar file exists on your server and note the location. If an invalid symbolic link exists in your $ORACLE_HOME/jdk/bin, remove the invalid symbolic link and recreate it to point to the actual location of the JDK on the server. Try applying the patch again. If the patch still fails, try applying the patch again but with the "-jdk" switch pointing to the actual location of the jar file. If none exists, you may have to download and install JDK from your OS vendor's Web site.
If this does not resolve the problem, you should open an iTAR with Oracle Support and they will help you to resolve this.
