2.4.8 Fatal error when file is empty

[dspiegel]

Started getting errors this week following composer update of my project. I have tracked issue down to 2.4.8 yuicomposer.jar. 2.4.7 does not have issue. Fatal error occurs when empty js file is compressed. This empty placeholder file has been in my project for over 6 months without any issues. Now I cannot complete assetic:dump of Symfony2 project.

Ran test on command line using empty js or js with only comments and got same java error. Did not test css to see if it does the same.

Hmmm... Looks like an upstream bug :)
