NPE when reading a non-existent File

[basilevs]

IFile.getContents(false) throws NPE in a race with deletion operation.

Steps to reproduce

Paste Junit test in git/eclipse.platform/resources/tests/org.eclipse.core.tests.resources/src/org/eclipse/core/tests/resources/regression/IFileTest.java and run it

	@Test
	public void coreExceptionFromGetContentsForDeleted() throws CoreException {
		IProject project = getWorkspace().getRoot().getProject("MyProject");
		IFile subject = project.getFile("subject.txt");
		Job noise = Job.create("Create/delete", monitor -> {
			try {
				while (!monitor.isCanceled()) {
					createInWorkspace(subject);
					subject.delete(true, null);
				}
			} catch (CoreException e) {
				return e.getStatus();
			}
			return Status.OK_STATUS;
		});
		noise.setPriority(Job.INTERACTIVE);

		long stop = currentTimeMillis() + 1000;
		try {
			noise.schedule();
			while (currentTimeMillis() < stop) {
				assertContentAccessibleOrNotFound(subject); // should not throw
			}
		} finally {
			noise.cancel();
		}
	}

	/**
	 * @param file
	 *            - a resource to read
	 */
	private void assertContentAccessibleOrNotFound(IFile file) {
		try (InputStream contents = file.getContents(false)) {
			contents.transferTo(OutputStream.nullOutputStream());
		} catch (IOException e) {
			throw new AssertionError(e);
		} catch (CoreException e) {
			switch (e.getStatus().getCode()) {
			case IResourceStatus.RESOURCE_NOT_LOCAL:
			case IResourceStatus.RESOURCE_NOT_FOUND:
			case IResourceStatus.FAILED_READ_LOCAL:
			case IResourceStatus.OUT_OF_SYNC_LOCAL:
				break;
			default:
				throw new AssertionError(e);
			}
		}
	}

Expected result

CoreException is occasionally thrown

Actual result
