Hi, I have a problem with workspace resource locks.

My plugin defines a custom classpath container. During the call to IClasspathContainer.getClasspathEntries(), I have to call some third party code which fiddles with the file system using the java.io.File API. Fortunately I know exactly which files it changes, so I would like to call IFile.refreshLocal() to make the workspace aware of those changes.

Unfortunately, the getClasspathEntries() method is called in the context of a lock on the Project. Calling refreshLocal also tries to lock the Project, but even though I am on the same thread the lock is not reentrant, so my code hangs indefinitely waiting for itself to finish!

Is there any way to perform the refresh without obtaining a new lock?

Many thanks,
Neil
