NullPointerException on startup when having symbolically linked directories (non-relative) in the repository folder

[gitblit]

Originally reported on Google Code with ID 595

What steps will reproduce the problem?

1.
/tools/repository/test1.git
/tools/repo/test2.git

2. create a symlink in /tools/repository to the 'other' git repo
cd /tools/repository/
ln -s /tools/repo/test2.git

3. use 
"gitblit.properties"
git.repositoriesFolder = /tools/repository/

4. start gitblit (standalone or within tomcat)

1.6.1, 1.6.2, 1.6.3.snapshot

The error happens in JGitUtils.java:529
FileUtils.getRelativePath(baseFile, file); will return null for the sym-link, which
then later results in the NPE when sorting the repository names.

                        // determine repository name relative to base path
                        String repository = FileUtils.getRelativePath(baseFile, file);

Try the develop branch.

Looks like a duplicate of issue #837
