Here's a code snippet, which uses JGit's ListBranchCommand to list existing remote branches and creates them locally. Although the tracking option is set prior the call to branchCreateCmd.call(), no tracking configuration is written to .git/config.

try {
        // get a list of branches
        ListBranchCommand branchList = git.branchList();
        branchList.setListMode(ListMode.REMOTE); // want all remote branches
        List<Ref> remoteRefs = branchList.call();
        for (Ref remoteRef: remoteRefs) {
        String name = remoteRef.getName();
        int remoteIndex = (Constants.R_REMOTES + "origin/").length(); //$NON-NLS-1$
        // Remove "refs/remotes/origin/" part in branch name
        name = name.substring(remoteIndex);
        if (!name.equals(Constants.MASTER)) {
                CreateBranchCommand branchCreateCmd = git.branchCreate();
                branchCreateCmd.setName(name);
                RevWalk walk = new RevWalk(git.getRepository());
                RevCommit startCommit = walk.parseCommit(remoteRef
                .getObjectId());
                branchCreateCmd.setStartPoint(startCommit);
                // Add remote tracking config
                branchCreateCmd.setUpstreamMode(SetupUpstreamMode.TRACK);
                branchCreateCmd.call();
        }
        }
} catch (IOException ioException) {
        ioException.printStackTrace();
} catch (JGitInternalException e) {
        e.printStackTrace();
} catch (RefAlreadyExistsException e) {
        e.printStackTrace();
} catch (RefNotFoundException e) {
        e.printStackTrace();
} catch (InvalidRefNameException e) {
        e.printStackTrace();
}


Replacing

RevWalk walk = new RevWalk(git.getRepository());
RevCommit startCommit = walk.parseCommit(remoteRef
                .getObjectId());
branchCreateCmd.setStartPoint(startCommit);

with

branchCreateCmd.setStartPoint(remoteRef.getName());

works.
