ISVNClientAdapter limitations (getCopy, doExport)

Hello,
I've found a couple of limitations to the ISVNClientAdapter interface, and wanted to get feedback on these to see if they are indeed limitations, if they are known, and if fixes are in the near future.

First, neither of the ISVNInfo.getCopyUrl() and ISVNInfo.getCopyRev() methods seem to work. The first always returns null, and the second always returns 0. I'm assuming the following code should work:

        SVNUrl srcUrl = …
        SVNUrl destUrl = …
        SVNRevision srcRevision = ...

        adapter.copy(srcUrl, destUrl, "…", srcRevision);
       
        ISVNInfo destInfo = adapter.getInfo(destUrl);
        SVNUrl expectedSrcUrl = destInfo.getCopyUrl();
        boolean copied = expectedSrcUrl.equals(srcUrl); // this should return true

Instead, this throws a NullPointerException because "expectedSrcUrl" is null.

Second, the ISVNClientAdapter.doExport(…) does not support a non-recursive export. The JavaSVN API supports this, is there a reason ISVNClientAdapter doesn't?

Thanks,
Tom
