How to do Always Use a Finally Clause In Each Method to Cleanup in java

Always Use a Finally Clause In Each Method to Cleanup

In Java, it is impossible to leave the try or catch blocks (even with a throw or return statement) without executing the finally block. If for any reason the instance variables cannot be cleaned, throw a catch-all exception that should cause the caller to discard its object reference to this now corrupt object. 

If, for any reason the static variables cannot be cleaned, throw an InternalError or equivalent that will ultimately result in restarting the now corrupt JVM.
