IO exception

[Pouja]

There can be an io exception when there is no sourcemap given nor there is a source map file.
The following stacktrace will be reproduced (I have ommited some parts of the file path) :

ERROR in ./src/main/javascript/app/components/path/traffic-diensten.component.js
Module build failed (from ./node_modules/coverage-istanbul-loader/lib/index.js):

Thanks for the bug report! Do you have time to submit a PR?

I actually do. I'll try to come with a PR this week.
