Probably needs some evalution by CND guys, I don't see anything wrong in module system from the messages recorded at

http://statistics.netbeans.org/exceptions/messageslog?id=679271
Comment 3 Vladimir Voskresensky 2013-07-09 06:24:58 UTC 
Message log shows that 
DataObject$ModifiedRegistry starts to fire change events.

And just before that all cnd modules are turned off

And after DataObject$ModifiedRegistry modify we see that 
module system has problems renaming all-layers.dat and then report about own activity as
Long time unused modules found, disabling.
Most probably turning off and change events are done in parallel, so classes are partialy unloaded.

Any ideas what can be done on CND side?
Comment 4 Jaroslav Tulach 2013-07-09 17:08:14 UTC 
But we don't support turning modules off in running IDE! Reporter, what action could trigger turning off the C/C++ support?
Comment 5 Jaroslav Tulach 2013-07-09 17:11:15 UTC 
Maybe this is somehow related to bug 232456? Maybe the ISE causes disablement of the modules!?
