NullPointerException when reviewing CCFinderX inputs

[starlocke]

Steps to reproduce:

1. Have Docker installer.

2. Host computer (assuming bash shell):

   git clone https://github.com/starlocke/flow.git
   cd flow
   docker run -it --rm --name ccfx -v $(pwd):/project kyoheif/ccfx /bin/bash

3. Docker container instance:

   cd projects
   /usr/src/ccfx/ccfx-master/ubuntu32/ccfx d java -dn /project
   ls -lA

   • a.ccfxd and .ccfxprepdir should now exist

4. On the host computer, load the flow project into Eclipse having JDeodorant.

5. Load the CCFX files as input into JDeodorant (Duplicated Code utility tab), for example, and "Finish":

   • C:\Projects\flow\a.ccfxd
   • C:\Projects\flow\.ccfxprepdir

6. Double-clicked a clone's row (Duplicated Code utility tab) with the intent to jump directly to that source code line.

7. ERROR: NullPointException happened instead of a file editor opening up and jumping to the clone. EXPECTED: jump to a source code file directly to the clone's line.
