>> Test authors usually specify the name of a test class to be run by `jtreg` 1:1 in a `@run` action directive. This PR introduces the new test property `test.main.class` and tries to initialize it with the fully-qualified class name of the test class. It is composed of the package name and the truncated file name of `.java` source file passed to `jtreg`: `SomeTest.java` becomes `SomeTest`
