There is a deadlock when running tests for projects/compilation module, it seems to occure under both jdk 1.3.1_02 and 1.4.1. It seems it is caused by synchronization in ProjectMember$Evnironment class. The threads in deadlock are the 'FolderRecognizer' (as usually) and 'ContainersList-Updater'. The 'FolderRcognizer' thread creates BTDataObject which creates the ProjectMember for itself in its ctor, but the 'ContainersList-Updater' tries to access Lookup of another PM which keeps the lock and indirectly asks some DataFolder for its children. Several bad things happend at the same time: 1. BTDataObject does something in its ctor, this should be avouded (especially calls to another 'higher' layer; the projects in this case) 2. ProjectMember$Environment performs wrong synchronization in beforeLookup method, this is probably the root cause. 3. The core/naming (DOEnum) uses DataSystems (DataFolder.getChildren) to get the list of bidings in the Context. It's unnecessary and it's done this way just for the files ordering.
