That is mostly true. The compatibility you speak of is that the Java
source code level. Due to the way JNI works you must have the same
x.y version of the JavaHL JAR as your native libraries or the native
method calls will not match up. The .z should not matter though.
The original question references the server and repository. Those can
be any 1.x version as Subversion compatibility rules dictate that
any1.x client can talk to any 1.x server. The main thing that matters
is that your JAR matches up with the native libraries being used on
the client where the JAR is used.
