You can try to run the jtreg tests.

There are instructions on running the tests in {top}/common/doc/testing.* and {top}/common/doc/building.*

You’ll have to download http://openjdk.java.net/jtreg <http://openjdk.java.net/jtreg> in order to run these tests.

Bob.

Once you become an "author" in any of the OpenJDK projects, you get a user name and should be able to publish reviews on cr.openjdk.java.net <http://cr.openjdk.java.net/><http://cr.openjdk.java.net <http://cr.openjdk.java.net/>>. Before that, if the patch is small, it can be posted inline in an email to the list. If it's large, you will need a current OpenJDK user to host it for you. At least that's how I understand it. Hopefully someone who knows the process better can chime in here.

On the other hand, this stuff is weird, we're misusing the C preprocessor to process defines in java code, so I'm not suprised it breaks down. I don't know why it succeeded when run on the command line, though. My suggestion is to just do some quick and dirty hack around this: take the file you manage to generate and just copy it in during the build instead.
