Copyright protects against verbatim copies of original work, it does not 
disallow somebody to make a different original work  that 
functions/looks/feels identically. That is what patents are for.

All the Java Code you write is automatically copyrighted. Nobody is 
allowed to copy and distribute it without the permission of the owner.

However, if your Java Code implements a CompressByFactorMillion 
interface, everybody is allowed to write his own implementation of that 
interface. But if your implementation uses a certain algorith for that 
compression (such as throw away everything except every milliont byte), 
you can patent that algorithm. That would disallow people to use that 
algorithm even when they use C instead of Java.

Macromedia probably does not have copyright on CFML. They do have 
copyright on their implementation (CF MX), the documentation, the 
specification etc. They might even have a patent on small things like 
certain compiler optimizations, or big things like on the concept of a 
tag based language for HTML preprocessing.

IANAL,
