You are misunderstanding. I am saying that the JAR could be from 1.2.0
and the library from 1.2.3 (or vice versa) and they would work fine. You
just cannot take a JAR from 1.1.x and use it with a 1.2.x library and vice
JavaHL uses JNI so the interface contract is fairly tight.
Finally, we are driving JavaHL pretty hard and constantly demanding new
features so we generally demand the very latest version in Subclipse. I
do not see that changing for a while.

There are no technical issues with this approach, it is simply that in the
case of Linux this is entirely under the control of the distribution
provider. There are no Subversion "binaries" for any platform other than
Windows. A company named Metissian has been providing them for OS X, but
in the Linux world it is up to the distro. Historically many
distributions will not include any software that requires Java because of
the licensing issues. This is getting better and there are more and more
options for JavaHL being made available in the distros.

No, the issue is that right now most of the commands do not have an --xml
option. Once they all do, I would expect this issue to get a lot better.
This adapter will always be the slowest but it should be possible for it
to become a lot more reliable.
