MacBook Pro 13 Haswell alarming heat issues

As you can see from menu bar where my temperatures are displayed, the temperatures my MacBook Pro 13 Haswell registers are rather worrying. I had two ppt files up, Safari with a few tabs, Spotify running in the background and doing my work on NetBeans IDE. I was wrote a simple Java console application on NetBeans and compiled it. There was a problem with one of the loops which caused it run infinitely. This is turn caused my temperature to spike up fast and so high. It reach 101 degree celsius at one point. Can anyone enlighten me on this, is this normal or should I be doing something about it?
