Is it possible for the same javac compiler to compile the same set of source files but produce class files of different checksums?

Question

I was attempting to compare the results of this: (in ant)

Answer 1

as you showed, the difference is in the generated constant pool, which is really a non-issue, but troubling as you would expect the same output with the same compiler and options. i would bet that the compiler is called with the java files in different order between the two situations, and the order of compilation is affecting the result.
