Both the fix and the test look good. I left two minor formatting comments, but I'll approve it as-is. If you want to fix them, I'll re-approve.

tests/manual/desktop/HostServices/HostServicesShowDocumentTest.java line 42:

> 40:     private final static String testHtmlUri = new File("test.html").toURI().toString();
> 41:     private final static String testTxtUri  = new File("test.txt").toURI().toString();

Minor: the preferred order for modifiers is `private static final`.

tests/manual/desktop/HostServices/test.txt line 2:

> 2: Test page for HostServices.showDocument.

Minor: It doesn't show up in the UI, but this file doesn't have a newline at the end of file
