New JITWatch release 1.2.1 - UI improvements

[Chris Newland]

Hi all,

I've been tidying up the JITWatch UI and have completed a "focus-link" system where changing the selected compilation in any of the UI screens will update all of the other screens to show that compilation.

Hope you find that useful.

Next up I'm going to be improving the visualisations around OSR (On-Stack-Replacement) compilations and then attempting to highlight loop unrolling.

Now JDK9 is out I'll also start picking up some of the new LogCompilation info output by the latest HotSpot code.

Cheers,

Chris
