Hi guys,

I have now been working for months with my eclipse installation. This morning however it doesn't start up correctly anymore.
I can see the ui, but can't see any files of my project in project explorer. The opened file editors remain empty and I get the following error message everywhere (and if I try to refresh, rebuild index or do something else I get other error messages. Nothing works!):

eclipse.buildId=M20090211-1700
java.version=1.6.0_0
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=de_DE
Command-line arguments:  -os linux -ws gtk -arch x86_64

I have no clue where this comes from. To give some hints what I did in the last couple of days: several days ago I installed the intel compiler plugin, but afterwards eclips still worked for several days correctly.
Yesterday I tried some changes in the projects indexer settings, but set it back to the defaults in the end.

Can anyone give me some hint how to fix this?


Since the top of the stack is CConfigurationDescriptionCache.loadData, I would venture a guess that a configuration description cache is unable to load its data. Presumably it's a CDT configuration description, since the package is org.eclipse.cdt.yadayada.

So, you might try searching Bugzilla to see if anyone else has encountered this (I would suggest searching within the CDT project for bugs with CConfigurationData and loadData in the description text). Also, you might want to take a look at the eclipse.tools.cdt newsgroup to see if anyone else is reporting this, and if you don't find an existing thread on it, post a question there.
