Hi All and Happy Hols,
My big picture: I am _trying_ to migrate Apache Commons VFS tests from SSH Core
0.8.0 (!) and Mina Core 2.1.x.
I've given up for now on migrating from SSH Core 0.8.0 to 2.x because it seems
like a rewrite beyond my sshd foo ATM.
To migrate from Mina Core 2.1.10 to 2.2.4 there is some behavioral breakage
that I am trying to resolve.
One of the items that sticks out is:
Exception in thread "pool-3-thread-1" java.lang.NoSuchFieldError: Class

So that means that Mina's ftpserver is not compatible with mina-core, not great.
So I go over to ftpserver and try to compile 1.2.x and it breaks because we've
(at least) move a public class from one package to another, _not in a major
release_, and JApiCmp is set up to fail on binary incompatibilities.
So:
- Should I fix 1.2.1-SNAPSHOT to make it not break BC?
- Should we declare a BC policy or just keep randomly breaking stuff?
TY!
