Description
Preconditions: an Eclipse project imported inside the workspace
Steps to reproduce the problem:
- copy a set of model files via system file operations inside the project
- trigger an eclipse application (command line) that accesses the above project
Observed (random) behavior:
The following exception is thrown several times (once for each file copied via file-system operations):
BundleException occurred when invoking code from unknown plug-in: Cannot transiently start a module whose start level is not met..
org.osgi.framework.BundleException: Cannot transiently start a module whose start level is not met.

Enabling tracing for the Equinox OSGi Framework (debug, debug/messageBundles, debug/startlevel, monitor/activation options), has shown that these exceptions happen on workspace shutdown.
The exceptions are thrown from org.eclipse.sphinx.emf.workspace.internal.loading.ModelLoadJob, a thread run asynchronously by LoadJobScheduler on org.eclipse.sphinx.emf.workspace.loading.LoadJobScheduler.scheduleModelLoadJob(FileLoadOperation), as a result of org.eclipse.sphinx.emf.workspace.loading.ModelLoadManager.loadFiles(Collection, boolean, IProgressMonitor) call from org.eclipse.sphinx.emf.workspace.internal.syncing.ModelSyncRequest.perform() (line 275).
Clearly, the execution of the job performing the sync should be aborted if the workspace is shutting done.
