Regression test for 6670162 failing on Firefox 3

Verification of the test case for 6670162 is failing on the Firefox 3 browser. This may indicate a recent and severe regression in LiveConnect functionality that may break real-world applets. It must be investigated immediately and the scope of the failure determined.
The test case fails intermittently in Internet Explorer as well, apparently in cold start situations where the JVM running the applet takes a long time to start up. This indicates a race condition in LiveConnect initialization which should not be present -- the first call from JavaScript to Java should block waiting for the applet to either successfully start or to produce an error during initialization.
