Build ID: M5

Steps To Reproduce:
I installed the XLC feature in the M5 candidate build. Clicking on it in the Properties Page gave this exception:

I can't reproduce this with HEAD.  I assume from the stack trace that you selected a source file from the Project Explorer and then opened the properties, but this works for me.

I've installed the M5 bits with all Features in a clean Eclipse configuration.
1) Create Hello World ANSI C Project
2)

Indeed. This is using Vivian's M5 candidate:
cdt-master-6.0.0-I200902031437

On MacOS:
1) I installed all the features from the update site to a clean configuration
2) I created the HelloWorld C ANSI program
3) Properties on hw.c
4) Try to access the XL C/C++ page

It works at the project root, but not at the file level.

Here's another exception from the same area (having pressed OK on that page):

Ah ok... I only fixed it this morning, so it wouldn't be in yesterday's build.
