I am not sure there is a problem. The call via

  On Start/Stop (27)  java.util.ArrayList.ensureCapacity
      java.util.ArrayList.ensureCapacity
      java.util.ArrayList.add
      org.openide.util.lookup.InheritanceTree$1TwoJobs.internal
      org.openide.util.lookup.InheritanceTree.classToNode
      org.openide.util.lookup.InheritanceTree.searchClass
      org.openide.util.lookup.InheritanceTree.lookup
      org.openide.util.lookup.InheritanceTree.registerReferenceToResult
      org.openide.util.lookup.DelegatingStorage.registerReferenceToResult
      org.openide.util.lookup.AbstractLookup.lookup

      org.openide.util.lookup.ProxyLookup$R.addLookupListener
      org.openide.filesystems.URLMapper.reset
      org.openide.filesystems.URLMapper.<clinit>
      org.openide.filesystems.FileObject.toURL

      org.netbeans.modules.project.libraries.LibrariesStorage.getLibraries
      org.netbeans.modules.project.libraries.LibrariesModule.run
      org.openide.util.RequestProcessor$Task.run
      org.openide.util.RequestProcessor$Processor.run

goes through AbstractLookup.lookup and that one is guarded by call to enterStorage(). The other call 

   main (15)  java.util.ArrayList.ensureCapacity
      java.util.ArrayList.ensureCapacity
      java.util.ArrayList.add
      org.openide.util.lookup.InheritanceTree$1TwoJobs.internal

      org.openide.util.lookup.AbstractLookup.lookupItem
      org.openide.util.lookup.AbstractLookup.lookup

      org.netbeans.core.startup.NbInstaller$1.run
      org.openide.filesystems.FileUtil$2.run
      org.openide.filesystems.EventControl.runAtomicAction
      org.openide.filesystems.FileSystem.runAtomicAction
      org.openide.filesystems.FileUtil.runAtomicAction
      org.openide.filesystems.FileUtil.runAtomicAction

      org.netbeans.core.startup.Main.getModuleSystem
      org.netbeans.core.startup.Main.getModuleSystem
      org.netbeans.core.startup.Main.start
      org.netbeans.core.startup.TopThreadGroup.run
      java.lang.Thread.run

goes through AbstractLookup.lookupItem and that one also calls enterStorage().

I may be overseeing something, but in my opinion the system is properly synchronized by the enter/exit Storage methods.
