The tests are in the jdk and hotspot repositories. To run the tests for 
java.lang and sub-packages then just do:

jtreg -jdk:<your-jdk> jdk/test/java/lang

or to run the compiler tests in the hotspot repo, just do:

jtreg -jdk:<your-jdk> hotspot/test/compiler

If you are trying your own HotSpot build then you'll probably want to 
specify the -vmoption to run the tests with various options. More 
information on the jtreg page [1]. Also Jon Gibbon has a blog with 
useful information on the various ways that tests can be run with jtreg.
