I hoping there was a technique I don't think default scope would work. Consider the case where multiple threads call the method in question. If the second thread over-writes the first thread's value before it gets used, you'll have serious errors. Something like a ThreadLocal is required here. Something that simulates the call stack frame. > that would behave like that, but which would not expose the variable > to the entire package, when really only one method should use that > variable. > > The techniques that I can think of are default scope variable or pass > value down call chain to where it is used. Are there any others? Is there any way you can show us the code? I'm curious as to why it's so hard to refactor.
