Subject [math] spinning BOBYQAOptimizerTest
Date Sun, 05 Aug 2012 22:13:33 GMT
The site build just hung on me due to
BOBYQAOptimizerTest.testConstrainedRosenWithMoreInterpolationPoints
spinning.  A sample thread dump showing the spinning thread is show
below.  Above the reference to
BOBYQAOptimizer.doOptimize(BOBYQAOptimizer.java:246), successive
dumps change.  The code continues to run, but does not complete. 
The hang happened during the coberta instrumented test run.
