MakeLogicalViewProvider.AnnotationUpdater MakeProject[M:\linuxsoftware\linlog@17307312:1b747c9] thread blocks all read access threads by accessing I/O in the write mode. org.netbeans.modules.cnd.makeproject.ui.LogicalViewChildren.createNodes() should be fast yet you're trying to normalize files inside. Please pre-compute outside of the lock.
