Fix pathname encoding in the component test library

[FWest98]

The component test library did not properly decode the URI file path, causing characters like spaces in the path to break tests. For example, in the old setup:

String testPath = testClass.getClassLoader().getResource(testClassResourceName).getFile();
// returns "/foo/foo%20bar/org/acme/Foo.class"

String testClassesRootPath = ...
// yields "/foo/foo%20bar"

testOutputDirectory = new File(testClassesRootPath);
// file not found, tests break

Any chance you could add a test for this?

[FWest98]

I was looking into that, but I think the only way to do so is to create a new subproject somewhere with a special character in its name, and then add a test there. I was not quite sure whether that's desired, and if so, how to proceed with that.

In case the extra subproject is still desired for this, could you give me some directions on how to approach it?
