returning copy of the repository list

[tulinkry]

• avoiding concurrent modification exception (when the list is modified later)

This piece of code in repos.jsp produces an CME when modifying the list of repositories (which is taken directly from the RE). Returning a copy solves the problem, the objects in the list are not modified.

List<RepositoryInfo> repos = pHelper.getRepositoryInfo(project);
String projDesc = project.getName();
Integer cnt = 0;
Collections.sort(repos, comparatorRepo); <!-- HERE -->
%>
<%
for (RepositoryInfo ri : repos) {
    if (cnt > 0 && ri.getParent() == null)
        // discard repositories without a parent url
        continue;
    if (cnt != 0) {
        projDesc = ri.getDirectoryName()
                     .replace(cfg.getSourceRootPath() + File.separator, "");
    }
    %>
