You got hit by https://bugs.eclipse.org/bugs/show_bug.cgi?id=296512. The good news is that it has been fixed in Mars.

My cdt suddenly does not start anymore. I updated to latest master and it start happening,

however I don't see any cdt changes that can cause that that happened recently.

Basically very nasty problem.

CDT declared template engine extension in cdt.core.

But this extension uses template attribute pagesAfterTemplateSelectionProvider

which must implement org.eclipse.cdt.ui.templateengine.IPagesAfterTemplateSelectionProvider

(ui!!)

Naturally this extension will be defined in ui plugin.

So what happens in startup PDOM indexer trying to pull project description, which
pulls template engine, which in turn in static initialize tried to load extension and RESOLVE
all classes. These classes defined in ui plugins, so eclipse trying to load ui plugins now, but
some stuff at the end wants to run in UI thread, and all these dies horrible death...

Do I miss something or how it does not blow up for other people?
