Sorry for now answering sooner. This is a test for
"openide.nodes/src/META-INF/upgrade/org.openides.nodes.Node.hint". It is parsed
by org.netbeans.modules.java.hints.declarative.test.TestParser.parse, and I
believe the parser should ignore everything before the first %%TestCase.
(In principle, the tests can be also run when the module tests are run, but
I doubt that is configured for the nodes module. So the way to run the test is
to open it in the IDE.)
