Building the latest mlvm on Mac OS X 10.6.8 works!

Adding the "coro" guard included CoroutineTest.java

The problem with the tests failing was due to jtreg not finding junit.

One solution is putting a copy of junit.jar in jtreg's lib/ dir:

$ curl -L http://sourceforge.net/projects/junit/files/junit/4.5/junit-4.5.jar -o jtreg/lib/junit.jar

Now all the invoke and coro tests pass.

This is what I am using to invoke jtreg:

JTREG_INVOKE="jtreg -XX:+UnlockDiagnosticVMOptions -XX:+UnlockExperimentalVMOptions -ignore:quiet -agentvm -jdk:$BUILD_HOME"

The tests run about 50% faster with the -agentvm argument.

The only failure now is running SingSet2 -- but that probably has nothing to do with mlvm.
