Fix Infinite loop on annotate classes

[asgraf]

Fixes #295

[dereuromark]

Are you sure we dont need try/catch?
What if the code is broken in that model? Will reflection not throw exception here?

[asgraf]

This is my first time writing any reflection code
I removed try catch because i assumed there will be no more runtime errors caused by instantiating class, but after second thought i think you are correct. If class has some syntax errors exception will be still thrown in that case.

I have readded try/catch block to the patch
