Expected behavior

scijava 29.2.1

Additional context
The failing test

	@Test
	public void testBadFormatIntensityImageCancelsPlugin() throws Exception {
		// SETUP
		final ImagePlus imagePlus = IJ.createImage("test", 3, 3, 3, 8);
		final File exceptionFile = mock(File.class);
		when(exceptionFile.getAbsolutePath()).thenReturn("file.foo");
		when(MOCK_UI.chooseFile(any(File.class), anyString())).thenReturn(
			exceptionFile);

		// EXECUTE
		final CommandModule module = command().run(
			AnalyseSkeletonWrapper.class, true, "inputImage", imagePlus,
			"pruneCycleMethod", "Lowest intensity voxel").get();

		// VERIFY
		assertTrue("Plugin should have cancelled", module.isCanceled());
		assertEquals("Cancel reason is incorrect", "Image format is not recognized",
			module.getCancelReason());
	}

This appears in the console:

[ERROR] Cannot create plugin: class='org.scijava.io.http.HTTPHandle', priority=0.0, enabled=true, pluginType=DataHandle
