#76 Empty repository cause NullPointerException

[Martin Majliš]

When I was writing test for bug 1874974 I found another problem.

Generating statistics from empty repository causes NullPointerException.

Exception in thread "main" java.lang.NullPointerException

I created a similar script on Windows and tried running it. I obtained:

Parsing SVN log 'c:\temp\svn\test2\testcheckout\svn.log' exclude pattern 'null'
Scheduled 0 svn diff calls on 0 threads.
Generating report for into c:\temp\svn\test2\testcheckout\output\
Using default CSS file (statcvs.css)
The repository object is not valid. Please check your settings.
Is the log file empty? Do you run from a checked out directory? Do you have non-committed items?

We would need to have someone on Linux test it out... but I think the issue is with the XML transformation engine, and not StatSVN directly.
