Description Alexander Simon 2015-09-17 14:27:17 UTC 
I'm investigating failed test:
org.netbeans.modules.cnd.repository.impl.ReopenRepositoryValidationFinal

The reason of failure is:
#diff ./testRepository/ModelBuiltFromRepository.out ./testRepository-2/ModelBuiltFromRepository.out
156403c156403
< 		DUMMY_FORWARD STRUCT _GMutex[ 2677:9/84433 - 2677:23/84447 ][glib.h 2677:9-2677:23] from /var/tmp/alsimon-cnd-test-downloads/pkg-config-0.25/glib-1.2.10/glib.h

> 		DUMMY_FORWARD STRUCT _GMutex[ 80:3/1778 - 80:17/1792 ][glibconfig.h 80:3-80:17] from /var/tmp/alsimon-cnd-test-downloads/pkg-config-0.25/glib-1.2.10/glibconfig.h

The forward class declaration is registered in the project container (if real class declaration have not been registered yet).
As result registration of _GMutex from glib.h or _GMutex from glibconfig.h depends on parsing order of headers.
This unpredictable behavior prevents creating test that checks on equals code model in two different parsing/reparsing sessions.
