Remove unused imports

[Emkas]

I've cleaned this type of warnings after importing project to Eclipse.

This is my first pull request in this project, so it more like exploring new ground.

Thanks a lot for your contribution! One thing that we need in order to accept it, is for you to accept the so-called ECA. This means creating an Eclipse account with the same email used for committing at https://www.eclipse.org, and from your profile page accepting the ECA.

Hmmm... I've changed an e-mail in this commit and register on eclipse.org with the same e-mail address. Yet, I cannot accept ECA:

Could not validate the users ECA sign-off status. Please ensure that the e-mail address of all contributing accounts match a valid Eclipse Foundation account with a valid ECA.

But an e-mail looks good: emilsierzega [at] gmail

I had a similar issue when I started with Mojarra and if I remember I had to update my commit with a signature after I signed the ECA. I will try and find the command someone had me run

Here it is. I had to watch this video to fix mine

Thanks for the tip!

It's OK now. My fault that I didn't read CONTRIBUTING more carefully :-)
